Relationship between Big Data, Data Science and ML

Data is all over the place. Truth be told, the measure of advanced data that exists is developing at a fast rate, multiplying like clockwork, and changing the manner in which we live. Supposedly 2.5 billion GB of data was produced each day in 2012.

An article by Forbes states that Data is becoming quicker than any time in recent memory and constantly 2020, about 1.7MB of new data will be made each second for each person on the planet, which makes it critical to know the nuts and bolts of the field in any event. All things considered, here is the place of our future untruths.

Machine Learning, Data Science and Big Data are developing at a cosmic rate and organizations are presently searching for experts who can filter through the goldmine of data and help them drive quick business choices proficiently. IBM predicts that by 2020, the number of employments for all data experts will increment by 364,000 openings to 2,720,000

Big Data Analytics

Big Data

Enormous data is data yet with a tremendous size. Huge Data is a term used to portray an accumulation of data that is enormous in size but then developing exponentially with time. In short such data is so huge and complex that none of the customary data the board devices can store it or procedure it productively.

Kinds Of Big Data

1. Structured

Any data that can be put away, got to and handled as a fixed organization is named as structured data. Over the timeframe, ability in software engineering has made more noteworthy progress in creating strategies for working with such sort of data (where the configuration is notable ahead of time) and furthermore determining an incentive out of it. Be that as it may, these days, we are predicting issues when the size of such data develops to an immense degree, regular sizes are being in the anger of different zettabytes.

2. Unstructured

Any data with obscure structure or the structure is delegated unstructured data. Notwithstanding the size being colossal, un-organized data represents various difficulties as far as its handling for inferring an incentive out of it. A regular case of unstructured data is a heterogeneous data source containing a blend of basic content records, pictures, recordings and so forth. Presently day associations have an abundance of data accessible with them yet lamentably, they don’t have a clue how to infer an incentive out of it since this data is in its crude structure or unstructured arrangement.

3. Semi-Structured

Semi-structured data can contain both types of data. We can see semi-organized data as organized in structure however it is really not characterized by for example a table definition in social DBMS. The case of semi-organized data is a data spoken to in an XML document.

Data Science

Data science is an idea used to handle huge data and incorporates data purifying readiness, and investigation. A data researcher accumulates data from numerous sources and applies AI, prescient investigation, and opinion examination to separate basic data from the gathered data collections. They comprehend data from a business perspective and can give precise expectations and experiences that can be utilized to control basic business choices.

Utilizations of Data Science:

  • Internet search: Search motors utilize data science calculations to convey the best outcomes for inquiry questions in a small number of seconds.
  • Digital Advertisements: The whole computerized showcasing range utilizes the data science calculations – from presentation pennants to advanced announcements. This is the mean explanation behind computerized promotions getting higher CTR than conventional ads.
  • Recommender frameworks: The recommender frameworks not just make it simple to discover pertinent items from billions of items accessible yet additionally adds a great deal to the client experience. Many organizations utilize this framework to advance their items and recommendations as per the client’s requests and the significance of data. The proposals depend on the client’s past list items

Machine Learning

It is the use of AI that gives frameworks the capacity to consequently take in and improve for a fact without being unequivocally customized. AI centers around the improvement of PC programs that can get to data and use it learn for themselves.

The way toward learning starts with perceptions or data, for example, models, direct involvement, or guidance, so as to search for examples in data and settle on better choices later on dependent on the models that we give. The essential point is to permit the PCs to adapt naturally without human mediation or help and alter activities as needs are.

ML is the logical investigation of calculations and factual models that PC frameworks use to play out a particular assignment without utilizing unequivocal guidelines, depending on examples and derivation. It is viewed as a subset of man-made reasoning. AI calculations fabricate a numerical model dependent on test data, known as “preparing data”, so as to settle on forecasts or choices without being expressly modified to play out the assignment.

The relationship between Big Data, Machine Learning and Data Science

Since data science is a wide term for various orders, AI fits inside data science. AI utilizes different methods, for example, relapse and directed bunching. Then again, the data’ in data science might possibly develop from a machine or a mechanical procedure. The principle distinction between the two is that data science as a more extensive term centers around calculations and measurements as well as deals with the whole data preparing procedure

Data science can be viewed as the consolidation of different parental orders, including data examination, programming building, data designing, AI, prescient investigation, data examination, and the sky is the limit from there. It incorporates recovery, accumulation, ingestion, and change of a lot of data, on the whole, known as large data.

Data science is in charge of carrying structure to huge data, scanning for convincing examples, and encouraging chiefs to get the progressions adequately to suit the business needs. Data examination and AI are two of the numerous devices and procedures that data science employments.

Data science, Big data, and AI are probably the most sought after areas in the business at the present time. A mix of the correct ranges of abilities and genuine experience can enable you to verify a solid profession in these slanting areas.

In this day and age of huge data, data is being refreshed considerably more every now and again, frequently progressively. Moreover, much progressively unstructured data, for example, discourse, messages, tweets, websites, etc. Another factor is that a lot of this data is regularly created autonomously of the association that needs to utilize it.

This is hazardous, in such a case that data is caught or created by an association itself, at that point they can control how that data is arranged and set up checks and controls to guarantee that the data is exact and complete. Nonetheless, in the event that data is being created from outside sources, at that point there are no ensures that the data is right.

Remotely sourced data is regularly “Untidy.” It requires a lot of work to clean it up and to get it into a useable organization. Moreover, there might be worries over the solidness and on-going accessibility of that data, which shows a business chance on the off chance that it turns out to be a piece of an association’s center basic leadership ability.

This means customary PC structures (Hardware and programming) that associations use for things like preparing deals exchanges, keeping up client record records, charging and obligation gathering, are not appropriate to putting away and dissecting the majority of the new and various kinds of data that are presently accessible.

Therefore, in the course of the most recent couple of years, an entire host of new and intriguing equipment and programming arrangements have been created to manage these new kinds of data.

Specifically, colossal data PC frameworks are great at:

  • Putting away gigantic measures of data:  Customary databases are constrained in the measure of data that they can hold at a sensible expense. Better approaches for putting away data as permitted a practically boundless extension in modest capacity limit.
  • Data cleaning and arranging:  Assorted and untidy data should be changed into a standard organization before it tends to be utilized for AI, the board detailing, or other data related errands.
  • Preparing data rapidly: Huge data isn’t just about there being more data. It should be prepared and broke down rapidly to be of most noteworthy use.

The issue with conventional PC frameworks wasn’t that there was any hypothetical obstruction to them undertaking the preparing required to use enormous data, yet by and by they were excessively moderate, excessively awkward and too costly to even consider doing so.

New data stockpiling and preparing ideal models, for example, have empowered assignments which would have taken weeks or months to procedure to be embraced in only a couple of hours, and at a small amount of the expense of progressively customary data handling draws near.

The manner in which these ideal models does this is to permit data and data handling to be spread crosswise over systems of modest work area PCs. In principle, a huge number of PCs can be associated together to convey enormous computational capacities that are similar to the biggest supercomputers in presence.

ML is the critical device that applies calculations to every one of that data and delivering prescient models that can disclose to you something about individuals’ conduct, in view of what has occurred before previously.

A decent method to consider the connection between huge data and AI is that the data is the crude material that feeds the AI procedure. The substantial advantage to a business is gotten from the prescient model(s) that turns out toward the part of the bargain, not the data used to develop it.

Conclusion

AI and enormous data are along these lines regularly discussed at the same moment, yet it is anything but a balanced relationship. You need AI to get the best out of huge data, yet you don’t require huge data to be capable use AI adequately. In the event that you have only a couple of things of data around a couple of hundred individuals at that point that is sufficient to start building prescient models and making valuable forecasts.

The need for high-quality chatbot training data

Humans and computers have been interacting ever since the beginning and this interaction has been improving with innovation over the years. From setting medical appointments to doing online check-ins for flights, AI chatbots that imitate human conversations have been gaining momentum.

What is a Chatbot?

A chatterbot, also known as a chatbot is a software of Artificial Intelligence that can simulate a chat or conversation with a user. The medium used is a natural language through applications, websites or telephone conversations. If it is to be defined technically, a chatbot is simply a representation of the natural evolution of a system made solely for answering questions using Natural Language Processing (NLP).

Chatbots learn from interactions and grow with time. Their working is based on rule-based and smart machine working. Rule-based chatbots use predefined responses from a database. The database is searched using keywords. Smart machine-based chatbots use Artificial Intelligence and Cognitive Computing. They develop according to the interactions.

what is a chatbot

So, why are chatbots so popular?

Artificial intelligence finds its application in several fields. Chatbots are one of the most popular examples of Artificial Intelligence. They are an important asset for many businesses as they assist in customer support. According to a 2011 research by Gartner, around 85% of our interactions will be handled by bots rather than humans. Chatbots aren’t just used for answering questions, but also play a vital role in collecting information about them, creating databases, etc.

Chatbots help with:

  • Customer service marketplace’s first priority is its customers. Their experience determines the success or failure of a company. When online shopping is considered, it has been observed that most of the shoppers need some kind of support. They need help at each step of the purchasing process, which is where chatbots come into action and make the process smooth and quick.
  • Customer information strategizes their customer service based on the data that they collect about the consumers. Chatbots take information from the reviews and feedback and use the information to help determine how the company can make its product better.
  • Lesser workforce work done by one chatbot is better than getting it done by a large number of employees. Companies can cut down on costs by using chatbots that can handle a variety of customer interactions, thus making the work simpler and more efficient as human errors are reduced.
  • Avoids redundancy tasks can be avoided within company call centers and the employees, that is, they will help in ensuring that the employees spend their time on important tasks rather than repetitive tasks.

Chatbots today can answer simple questions using prebuilt responses. If a user says A, respond with B and so on. After this kind of development, expectations have increased. We look for more advanced chatbots which can perform several tasks.

Conversational AI chatbots can be divided into a number of categories based on their level of maturity:

Level 1: This is the basic level where the chatbot can answer questions with pre-built responses. It is capable of sending notifications and reminders.

Level 2: At this level, the chatbot can answer questions and can also improvise a little during a follow-up.

Level 3: The assistant is now capable of engaging in a conversation with the user wherein it can offer more than the prebuilt answers. It gets an idea of the context and can help you make decisions with ease.

Level 4: Now, the conversational chatbot knows you better. It knows your preferences and can make recommendations based on them.

Level 5 and beyond: Now the assistant is capable of monitoring several assistants to perform certain tasks. They can do efficient promotions, help in specific targeting of certain groups based on trends and feedback.

So, what goes on behind building a chatbot?

Building a conversational chatbot is a long process, which needs innovation at every step. The first and the most important decision to be made is how the bot will process the inputs and produce the reply. Most systems today used rule-based or retrieval-based methods. Other areas of research are grounded learning and interactive learning.

  1. Rule-based
    The chatbots are trained using a set of rules that automatically convert the input into a predefined output or action. It is a simple system, but highly dependent on keywords.
  2. Retrieval-based
    In this system, the bot on receiving the input locates the best response from a database and displays it. It requires a high level of data pre-processing. This system is difficult to personalize and scale.
  3. Generative
    As the demand for chatbots is increasing, more innovation is demanded. The limitations of the above-mentioned systems are overcome by this one. The bot is trained using a large amount of chatbot training data. Generative systems are trained end-to-end instead of step-by-step. The system remains scalable in the long run.
  4. Ensemble
    All advanced chatbots like Alexa have been built with ensemble methods, which are a mixture of all the three approaches. They use different approaches for different activities. These methods still need a lot of work.
  5. Grounded learning
    Most human knowledge isn’t in the form of structured datasets and is present in the form of text and images. Grounded learning involves knowledge that is based on real-world conversations.

For a chatbot to function as per requirements, it is important to provide it with high-quality chatbot training data. What exactly is AI training data?

A chatbot converts raw data into a conversation. This raw data is unstructured. For example, consider a customer service chatbot. The chatbot needs to have a rough base of what questions people might ask and the answers to those questions. For this, it retrieves data from emails, databases or transcripts. This is the training data.

The process of formulating a response by a chatbot

The Importance of High-Quality Chatbot Training Data

Most of the chatbots today don’t work properly because they either have no training or use little data. The implementation of machine learning technology to train the bot is what differentiates a good chatbot from the rest.

Training is an on-going process. This development happens in 5 stages:

  1. Warm-up training
    The client data is used to start the chatbot. This is the first and most important step.
  2. Real-time training
    The incoming conversations are tracked and tell the bot what people are asking or saying, instead of working purely based on assumptions.
  3. Sentiment training
    The way people are talking to the bot is used to train language and functions. For example, an angry user is dealt with differently as compared to a happy user.
  4. Effectiveness training
    In this method, the result of the conversations is analyzed and the bot is trained accordingly to reach more people faster.

These are a few ways how high-quality chatbot training data can enable a conversational bot to produce optimal results. After this, the chatbot is checked for improvement at every stage. 

Chatbots make interactions between people and organizations simpler, enhancing customer service. They allow companies to improve their customer experience and efficiency. Human intervention is important in building, training and optimizing the chatbot system.

Common AI Training Data Challenges

AI is programmed to perform selective tasks, assigning new tasks can be challenging. The limited experience and data can create obstacles in training the machines for new and creative methods of using the accumulated data. The costs of implementing AI technology are higher restricting many from using it. Machines are likely to replace human jobs but on the other hand, we can expect quality work assigned to humans. Ultimately the induced thought process cannot replace what humans can do hence the machine cannot innovatively perform tasks.

AI can take immediate actions but the accuracy is related directly to the quality of data stored. If the algorithms suit the type of task you want the machines to perform, the results will be satisfactory else, dissatisfaction will mount.

Ten most common challenges companies face in AI training data:

  1. Volumes of Data: Repetitive learning is possible with the use of existing data, which means that a lot of data, is required for training. 
  2. Data Presentation: The computational intelligence, statistical insights, processing, and presentation of data are of utmost importance for establishing a relationship with data. Limited data and faulty presentation can interrupt the predictive analysis for which AI data is built.
  3. Proper use of Data: Automation based on the data, the base that improves many technologies. This data is useful in creating conversational platforms, bots, and smart machines.
  4. Variety of Data: AI needs data that is comprehensive to perform automated tasks. Data from computer science, engineering, healthcare, psychology, philosophy, mathematics, finance, food industry, manufacturing, linguistics, and many more areas are useful.
  5. AI Mechanics: We need to understand the mechanisms of artificial intelligence to generate, collect, and process data; for the computational procedures, we want to handle smartly. 
  6. Data Accuracy: Data itself is a challenge especially if erroneous, biased, or insufficient. Even unusable formats of data, improper labeling of data or the tools used in data labeling can affect the accuracy. Data collected vary in formats and quality as collected from diverse sources such as e-mails, data-entry forms, surveys, or company website. Consider the pre-processing requisites for bringing all the attributes to proper structures for making data usable. 
  7. Additional Efforts on Data: Nearly 63% of enterprises have to build automation technology for labeling and annotation. Data integration requires extra attention even before we start labeling.
  8. Data Costs: Data generation for AI is costly but implementing it in projects can result in cost reduction. Missing links of data can add to costs of data correction. The initial investment is huge hence; the process and strategies require proper planning and implementation.
  9. Procuring Data: Obtaining large data sets requires a lot of effort for companies. Other than that de-duplication, removing inconsistencies are some of the major and time-consuming activities. Transferring the learning from one set of data to another is not simple. Practical use of AI data in training is complex than it looks due to a variety of data sets on industries.
  10. Data Permissions: Personal data, if collected without permission, can create legal issues. Data theft and identity theft are some allegations, which no company would like to face. Choose the right data for representing that criteria or population. 

With a lack of training data or quality issues, can stall AI projects or be the principal reason for project failure. AI technology is reliable but the human capabilities are restricted with the dependencies they create.

5 common misconceptions about AI

Ever wondered what your life would be without those perky machines lying around which sometimes/most times replaced a significant part of your daily routine? In Terminology fancied by Scientists, we call them AI (Artificial Intelligence,) and in plain layman or lazy man terms that is us, we fancy calling them machines and bots.

Let’s define the exact meaning of AI in terms of science because I hate disappointing aspiring scientists out there who don’t take puns lightly. For those that do, welcome to the fraternity of loose and lost minds. Let’s get down to business, shall we?

Definition: Artificial Intelligence or machine intelligence, is intelligence demonstrated by machines in contrast to the natural intelligence displayed by humans. Colloquially, the term "artificial intelligence" is often used to describe machines (or computers) that mimic "cognitive" functions that humans associate with the human mind such as "learning" and "problem-solving.”

Isn’t it evident I copied the above definition from Wikipedia? And did your natural intelligence decipher the meaning of the definition stated above?

Let me introduce you to the lazy man definition of Artificial Intelligence. Like all engineering scholars, I will take the absolute pleasure of dismantling the words and assembling it together again.

Artificial – Non-Human, something that can’t breathe air or respond to a feeling. 

Intelligence – the ability to display intellect, sound reasoning, judgment, and a ready wit.

Put the two words together and voila! Artificially intelligent machines are capable of displaying or mimicking human intellect, sound reasoning, and judgment towards it's surrounding.

Now that we got the definition of AI out of the way, look around you, what do you see? What’s in your hands? Do you not spot a single electronic device or bots?

Things or machines work a lot differently in this era. You must be awestruck of the skyrocketing shiny monuments. The big bird moving 33,000ft above your head carrying humans from one country to another, hospitals treating the diseased and the ill with technology your mind can’t fathom.

Fast cars, microwave and yes, we no longer communicate using crows or pigeons we have cell phones!

Don’t be surprised if I reveal that these are the necessity and an extension to our lives. And no, we cannot live without them anymore.

Our purpose of life has changed drastically, growing crops and putting food on the table isn’t what give us lines on the forehead. We built replacement models that take care of that too. We are living in a fast lane where technology, eventually, will slingshot us to the moon or another planet.

With such a drastic rise in AI and the current trend where all companies want a piece of it, there are some misconceptions about AI as well. With this blog, I try to debunk the misconceptions highlighting both the positive and negative aspects of artificial intelligence.

“If these machines are handling even the simplest of tasks, what are people going to do? Is it the destruction of jobs?”

Fret not. If there is technological advancement, there are always career opportunities as it is the human mind that does the ‘thinking.’ You are the master of your creation.

In fact, in 2020 there will be 2.3 million new jobs available thanks to AI, which results in less muscle power and more brainpower.

“Can Artificial Intelligence solve any/all problems?“

This question is debatable, while AI is designed to assist and make our jobs easier, it cannot save a human being from rubbing off cancers and illness.

Human intelligence hasn’t discovered a way to program the bots to predict or diagnose illness proactively. One must remember, bots act on what is fed/programmed by humans.

“Is AI infallible?“

If you thought it was, then I have slightly bad news. Humans are in a common misconception assuming the machines are no less than perfection and display little to no mistake. The non-sentient systems are trained by us, data selected and curated by us, and human tendency is to make mistakes and learn from them.

Artificial Intelligence is just as good as the training data used, which is created by humans. Any mistake with the training data will reflect on the performance of the system and the technology will be compromised. Ensuring you use a high-quality training dataset is critical to the success of the AI system.

Speaking of data being compromised, during the 2016 presidential election campaign, we witnessed the information of US citizens being evaluated by gaining access to their social media accounts. To proactively block their social media feeds with ads that will prove to be of interest. Therefore, stealing away the votes from the opposition.

We call this “data/information manipulation.” Sadly, the downside of Artificial Intelligence.

“AI must be expensive.”

Well, implementing a fully automated system doesn’t come easy and doesn’t come cheap. But depending on the needs and goals of the organization, it may be entirely possible to adopt AI and get the desired results without breaking your treasure chest.

The key is for each business to figure out what they want and apply AI as needed, for their unique goals and company scale. If businesses can workout their scalability and incorporate the right Artificial intelligence, it can be economical in the long run.

“Will Artificial Intelligence be the end of humanity?”

We are a work in progress, standing at the foyer of technological advancements with a long way to go. But, much like the misconception about robots replacing humans in the workforce, the question is more of smoke in the mirror.

The AI in its current level is not fully capable of self-conscious and decision making. Don’t let Star Trek, Iron Man and Terminator movies fool you into believing bots will lose their nuts (literally and hypothetically) and foreshadow the destruction of humanity. On the flip side, it is the natural disasters the bots are being designed to protect us from.

Oh, look what’s in every body’s hand, it’s what we call a cell phone. A device primarily designed to communicate with people that are at a greater distance.

Communication takes place using microwaves, very different from sand waves. Look closely and you’ll see people doing weird things using their fingers on the cell phone and a weird thing hanging from their ears going through to the same device. Yes, these devices are their partners for life.

Here we are, say Konnichiwa to the lady, don’t touch her! She’s just a hologram.

Welcome to the National Museum of Emerging Science and Innovation simply known as the Miraikan (future museum) where obsessiveness over technology has led us to build a museum for itself.

There’s Asimo, the Honda robot and, what you’re looking at isn’t another piece of asteroid that struck earth years ago, it is Geo-Cosmos. A high-resolution globe displaying near real-time events of global weather patterns, ocean temperatures, and vegetation covering across geographic locations.

You must be contemplating why has mankind reached such level of advancement? Let’s go back to the last question “Will AI be the end of humanity?”

The seismometer, a device that responds and records the ground motions, earthquake, and volcanic eruptions. There are a lot of countries that have lost far too many lives to even comprehend the tragic events of active earthquakes.

This device is a way to predict and bring citizens of Japan to safe grounds. Artificial Intelligence will not be the end of humanity, it can, in fact, be the opposite and could be an answer to humanity’s biggest natural calamities and disasters.

The human mind is something to behold, from its complex neural nerves in the brain to the nerves connecting to every part of the body to achieve motor functions. To replicate or clone it using artificial chips and wires is nearly impossible in the current era but the determination we hold and our adamant nature drives us to dream, the dream of one day successfully cloning the human consciousness into nuts and bolts of a bot.

One day to look at the stars and send bots for space exploration. To look for a suitable second home in an event of space disasters that humans have no control over. And, why send bots into deep space and not humans to add a feather to the hat of achievement?

Simply because we breathe, we starve, and our very own nervous system advertently detects the brutal nature of space above the earth. In this case, Artificial Intelligence and robots are in fact helping humans explore the possibilities of life in outer space. Which is against the misconception that AI will be the end of humanity.

So, there we have it, all the major misconceptions about artificial intelligence and what the reality is. End of the day, it all comes down to how we incorporate artificial intelligence and what we use it for.

If used in the right way, there will be a revolution in the way humans work. Which makes it important for all of us to work on educating people about artificial intelligence and using it to make the world a better place.

Understanding the difference between AI, ML & NLP models

Technology has revolutionized our lives and is constantly changing and progressing. The most flourishing technologies include Artificial Intelligence, Machine Learning, Natural Language Processing, and Deep Learning. These are the most trending technologies growing at a fast pace and are today’s leading-edge technologies.

These terms are generally used together in some contexts but do not mean the same and are related to each other in some or the other way. ML is one of the leading areas of AI which allows computers to learn by themselves and NLP is a branch of AI.

What is Artificial Intelligence?

Artificial refers to something not real and Intelligence stands for the ability of understanding, thinking, creating and logically figuring out things. These two terms together can be used to define something which is not real yet intelligent.

AI is a field of computer science that emphasizes on making intelligent machines to perform tasks commonly associated with intelligent beings. It basically deals with intelligence exhibited by software and machines.

While we have only recently begun making meaningful strides in AI, its application has encompassed a wide spread of areas and impressive use-cases. AI finds application in very many fields, from assisting cameras, recognizing landscapes, and enhancing picture quality to use-cases as diverse and distinct as self-driving cars, autonomous robotics, virtual reality, surveillance, finance, and health industries.

History of AI

The first work towards AI was carried out in 1943 with the evolution of Artificial Neurons. In 1950, Turing test was conducted by Alan Turing that can check the machine’s ability to exhibit intelligence.

The first chatbot was developed in 1966 and was named ELIZA followed by the development of the first smart robot, WABOT-1. The first AI vacuum cleaner, ROOMBA was introduced in the year 2002. Finally, AI entered the world of business with companies like Facebook and Twitter using it.

Google’s Android app “Google Now”, launched in the year 2012 was again an AI application. The most recent wonder of AI is “the Project Debater” from IBM. AI has currently reached a remarkable position

The areas of application of AI include

  • Chat-bots – An ever-present agent ready to listen to your needs complaints and thoughts and respond appropriately and automatically in a timely fashion is an asset that finds application in many places — virtual agents, friendly therapists, automated agents for companies, and more.
  • Self-Driving Cars: Computer Vision is the fundamental technology behind developing autonomous vehicles. Most leading car manufacturers in the world are reaping the benefits of investing in artificial intelligence for developing on-road versions of hands-free technology.
  • Computer Vision: Computer Vision is the process of computer systems and robots responding to visual inputs — most commonly images and videos.
  • Facial Recognition: AI helps you detect faces, identify faces by name, understand emotion, recognize complexion and that’s not the end of it.

What is Machine Learning?

One of the major applications of Artificial Intelligence is machine learning. ML is not a sub-domain of AI but can be generally termed as a sub-field of AI. The field of machine learning is concerned with the question of how to construct computer programs that automatically improve with experience.

Implementing an ML model requires a lot of data known as training data which is fed into the model and based on this data, the machine learns to perform several tasks. This data could be anything such as text, images, audio, etc…

 Machine learning draws on concepts and results from many fields, including statistics, artificial intelligence, philosophy, information theory, biology, cognitive science, computational complexity and control theory. ML itself is a self-learning algorithm. The different algorithms of ML include Decision Trees, Neural Networks, SEO, Candidate Elimination, Find-S, etc.

History of Machine Learning

The roots of ML lie way back in the 17th century with the introduction of Mechanical Adder and Mechanical System for Statistical Calculations. Turing Test conducted in 1950 was again a turning point in the field of ML.

The most important feature of ML is “Self-Learning”. The first computer learning program was written by Arthur Samuel for the game of checkers followed by the designing of perceptron (neural network). “The Nearest Neighbor” algorithm was written for pattern recognition.

Finally, the introduction of adaptive learning was introduced in the early 2000s which is currently progressing rapidly with Deep Learning is one of its best examples.

Different types of machine learning approaches are:

Supervised Learning uses training data which is correctly labeled to teach relationships between given input variables and the preferred output.

Unsupervised Learning doesn’t have a training data set but can be used to detect repetitive patterns and styles.

Reinforcement Learning encourages trial-and-error learning by rewarding and punishing respectively for preferred and undesired results.

ML has several applications in various fields such as

  • Customer Service: ML is revolutionizing customer service, catering to customers by providing tailored individual resolutions as well as enhancing the human service agent capability through profiling and suggesting proven solutions. 
  • HealthCare: The use of different sensors and devices use data to access a patient’s health status in real-time.
  • Financial Services: To get the key insights into financial data and to prevent financial frauds.
  • Sales and Marketing: This majorly includes digital marketing, which is currently an emerging field, uses several machine learning algorithms to enhance the purchases and to enhance the ideal buyer journey.

What is Natural Language Processing?

Natural Language Processing is an AI method of communicating with an intelligent system using a natural language.

Natural Language Processing (NLP) and its variants Natural Language Understanding (NLU) and Natural Language Generation (NLG) are processes which teach human language to computers. They can then use their understanding of our language to interact with us without the need for a machine language intermediary.

History of NLP

NLP was introduced mainly for machine translation. In the early 1950s attempts were made to automate language translation. The growth of NLP started during the early ’90s which involved the direct application of statistical methods to NLP itself. In 2006, more advancement took place with the launch of IBM’s Watson, an AI system which is capable of answering questions posed in natural language. The invention of Siri’s speech recognition in the field of NLP’s research and development is booming.

Few Applications of NLP include

  • Sentiment Analysis – Majorly helps in monitoring Social Media
  • Speech Recognition – The ability of a computer to listen to a human voice, analyze and respond.
  • Text Classification – Text classification is used to assign tags to text according to the content.
  • Grammar Correction – Used by software like MS-Word for spell-checking.

What is Deep Learning?

The term “Deep Learning” was first coined in 2006. Deep Learning is a field of machine learning where algorithms are motivated by artificial neural networks (ANN). It is an AI function that acts lie a human brain for processing large data-sets. A different set of patterns are created which are used for decision making.

The motive of introducing Deep Learning is to move Machine Learning closer to its main aim. Cat Experiment conducted in 2012 figured out the difficulties of Unsupervised Learning. Deep learning uses “Supervised Learning” where a neural network is trained using “Unsupervised Learning”.

Taking inspiration from the latest research in human cognition and functioning of the brain, neural network algorithms were developed which used several ‘nodes’ that process information like how neurons do. These networks have multiple layers of nodes (deep nodes and surface nodes) for different complexities, hence the term deep learning. The different activation functions used in Deep Learning include linear, sigmoid, tanh, etc.…

History of Deep Learning

The history of Deep Learning includes the introduction of “The Back-Propagation” algorithm, which was introduced in 1974, used for enhancing prediction accuracy in ML.  Recurrent Neural Network was introduced in 1986 which takes a series of inputs with no predefined limit, followed by the introduction of Bidirectional Recurrent Neural Network in 1997.  In 2009 Salakhutdinov & Hinton introduced Deep Boltzmann Machines. In the year 2012, Geoffrey Hinton introduced Dropout, an efficient way of training neural networks

Applications of Deep Learning are

  • Text and Character generation – Natural Language Generation.
  • Automatic Machine Translation – Automatic translation of text and images.
  • Facial Recognition: Computer Vision helps you detect faces, identify faces by name, understand emotion, recognize complexion and that’s not the end of it.
  • Robotics: Deep learning has also been found to be effective at handling multi-modal data generated in robotic sensing applications.

Key Differences between AI, ML, and NLP

Artificial intelligence (AI) is closely related to making machines intelligent and make them perform human tasks. Any object turning smart for example, washing machine, cars, refrigerator, television becomes an artificially intelligent object. Machine Learning and Artificial Intelligence are the terms often used together but aren’t the same.

ML is an application of AI. Machine Learning is basically the ability of a system to learn by itself without being explicitly programmed. Deep Learning is a part of Machine Learning which is applied to larger data-sets and based on ANN (Artificial Neural Networks).

The main technology used in NLP (Natural Language Processing) which mainly focuses on teaching natural/human language to computers. NLP is again a part of AI and sometimes overlaps with ML to perform tasks. DL is the same as ML or an extended version of ML and both are fields of AI. NLP is a part of AI which overlaps with ML & DL.

7 Best Practices For Creating Training Data

The success of any AI or ML model is determined by the quality of the data used. A sophisticated model using a bad dataset would eventually fail to function the way it was expected to. With such models continually learning from the data provided, it’s necessary to build datasets that can help these model achieve their objectives. 

If you’re still unsure what training datasets are and why are they important to the success of your system. Here’s a quick read to get you up to speed with training data and building high-quality training sets.

While building a dataset sounds like a mundane and tedious task, it determines the success or failure of the model being built. To help you look past the dreadful hours spent on collecting, tagging, and labeling data, here are 7 things to follow when making training datasets. 

Avoid Target Leakage

When building training data for AI/ML models, it’s necessary to avoid any target leakage or data leakage. The issue of data leakage arises when the model is trained on parameters that might not be available during real-time prediction. Since the system already knows all possible outcomes, the output would be unrealistically accurate during training. 

Since data leakage causes the model to overrepresent its generalization error, making it useless for real-world applications. It’s necessary to remove any data from the training set that might not be known during real-time prediction to avoid target leakage issue. Furthermore, to mitigate the risks of data leakage, its necessary to involve business analysts and professionals with the domain expertise to be involved in all aspects of data science projects from problem specifications to data collection to deployment.  

Avoid Training-Serving Skew In Training Sets

Training-serving skew problem arises when the performance during training is different from the performance during serving. The most common reasons for this issue to arise are the discrepancy in how data is handled in training compared to serving, change in data between training and serving. And, the feedback loop between the model and algorithm. 

Exposing a model to training-serving skew can negatively impact the model’s performance, and the model might not function the way it’s expected to. One way to ensure you avoid training-serving skew is by measuring the skew. You can do this by, measuring the difference the performance on training data and the holdout data, the difference between holdout data and ‘next-day’ data, and the difference in performance between ‘next-day’ data and live data.

Make Information Explicit Where Needed 

As mentioned earlier, when working on data science projects, it’s important to involve business analysts and professionals of the domain to be part of the projects. Machine learning algorithms use a set of input data to create an output. This input data is called features, structured in the form of columns. 

Domain professionals can help in feature engineering, i.e., understanding those features that can make the model work. This helps in two primary ways, preparing proper input datasets compatible with the algorithm used and improving the accuracy of the model over time.

Avoid Biased Data When Building Training Sets

When building a training dataset for your AI/ML model, it’s important to make sure the training data is a representation of the entire universe of data. And, not biased towards a set of inputs. 

For example, an e-commerce website that ships products globally wants to use a chatbot to help its users shop better and faster. In such a scenario, if the training data is built only using exchanges/queries from customers of only one region. The system might throw exceptions when a customer from any other region interacts with the bot, given the nuances of language. So, to make sure the system is free of bias, the training data should contain exchanges of all kind of users the e-commerce shop caters to. 

Ensure Data Quality Is Maintained In Training Data 

As stated earlier, the quality of your training data is an essential factor in determining the accuracy and success of AI/ML models. A training dataset that’s filled with bias, and features not available in real-world scenarios would result in the model showing outputs that are far from ground-truths. 

We at Bridged.co have employed two ways of ensuring every dataset we deliver is of the highest quality – consensus approach, and sample review. These approaches make sure that the models trained using these datasets produce results as close to ground-realities as possible. 

Use Enough Training Data

It just isn’t enough to have good-quality data. The dataset you use to train your model must cover all possible variations of the features chosen to train the system. Failing to do so can cause the system function abnormally and produce inaccurate results.

The more features you use to train your model more the data that will be needed to sufficiently train the system. While there is no ‘one size fits all’ when deciding the size of training data. A good rule of thumb for classification models is to have at least 10 times the number of data as you have features, and for regression models, 50 times the number of data as you have features.

Set Up An In-house Workforce or Get A Fully-managed Training Data Solution Provider

Building a dataset is no overnight task. It’s a long tedious process that stretches on for weeks if not months. 

It would be ideal to have an ops team in-house whom you can train, monitor, and ensure the highest quality is maintained. However, it isn’t a scalable solution. 

You can also check out training data solution providers, such as ourselves, to help you with all your training data requirements. A fully-managed solution provider doesn’t just provide you with quality control but also ensure your requirements can be met even if at scale. 


It’s a no brainer that a good quality training dataset is fundamental to the success of your AI/ML systems. These important tips are bound to make sure the training data you build is of the highest quality and helps your system produce accurate results. 

Understanding training data and how to build high-quality training data for ai/ml models

We are living in one of the most exciting times, where faster processing power and new technological advancements in AI and ML are transcending the ways of the past. From conversational bots helping customers make purchases online to self-driving cars adding a new dimension of comfort and safety for commuters. While these technologies continue to grow and transform lives, what makes them so powerful is data.

Tons and tons of data.

Machine Learning systems, as the name suggests, are systems that are constantly learning from the data being consumed to produce accurate results.

If the right data is used, the system designed can find relations between entities, detect patterns, and make decisions. However, not all data or datasets used to build such models are treated equally.

Data for AI & ML models can be essentially classified into 5 categories: training dataset, testing dataset, validation dataset, holdout dataset, and cross-validation dataset. For the purpose of this article, we’ll only be looking at training dataset and cover the following topics.

What Is Training Data

Training data also called training dataset or training set or learning set, is foundational to the way AI & ML technologies work. Training data can be defined as the initial set of data used to help AI & ML models understand how to apply technologies such as neural networks to learn and produce accurate results.

Training sets are materials through which an AI or ML models learn how to process information and produce the desired output. Machine learning uses neural network algorithms that mimic the abilities of the human brain to take in diverse inputs and weigh them, to produce neural activations, in individual neurons. These provide a highly detailed model of how human thought process works.

Given the diverse types of systems available, training datasets are structured in a different way for different models. For conversational bots, the training set contains the raw text that gets classified and manipulated.

On the other hand, for convolution models using image processing and computer vision, the training set consists of a large volume of images. Given the complexity and sophistication of these models, it uses iterative training on each image to eventually understand the patterns, shapes, and subjects in a given image.

In a nutshell, training sets are labeled and organized data needed to train AI and ML models.

Why Are Training Datasets Important

When building training sets for AI & ML models, one needs huge amounts of relevant data to help these models make the most optimal decision. Machine learning allows computer systems to tackle very complex problems and deal with inherent variations of hundreds and thousands or millions of variables.

The success of such models is highly reliant on the quality of the training set used. A training set that accounts for all variations of the variables in the real world would result in developing more accurate models. Just like in the case of a company collecting survey data to know about their consumer, larger the sample size for the survey is, more accurate the conclusion will be.

If the training set isn’t large enough, the resultant system won’t be able to capture all variations of the input variables resulting in inaccurate conclusions.

While AI & ML models need huge amounts of data, they also need the right kind of data, as the system learns from this set of data. Having a sophisticated algorithm for AI & ML models isn’t enough when the data used to train these systems are bad or faulty. Training a system on a poor dataset or a dataset that contains wrong data, the system will end up learning wrong lessons, and generate wrong results. And eventually, not work the way it is expected to. On the contrary, a basic algorithm using a high-quality dataset will be able to produce accurate results and function as expected.

For example, in the case of a speech recognition system. The system can be made on a mathematical model to train the system on textbook English. However, this system is bound to show inaccurate results.

When we talk about language, there is a massive difference between textbook English and how people actually speak. To this add the factors – such as voice, dialects, age, gender – varying among speakers. This system would struggle to handle any cases or conversations that stray from the textbook English used to train it. For inputs having loose English or a different accent or use of slang, the system would fail to function for the purpose it was created.

Also, in a case, such a system is used to comprehend a text chat or email it would throw unexpected results. As a system trained in textbook English would fail to account for abbreviations and emojis used, which are commonly used among people in everyday conversations.

So, to build an accurate AI or ML model, it’s essential to build a comprehensive and high-quality training dataset. To help these systems learn the right lessons and formulate the right responses. While it’s a substantial task to generate such a high volume of data, it is necessary to do so.

How To Build A Training Dataset

Now, that we have understood why training data are integral to the success of an AI or ML model, it’s necessary to know how to build a training dataset.

The process of building a training dataset can be classified into 3 simple steps: data collection, data preprocessing, and data conversion. Let’s take a look at each of these steps and how it helps in building a high-quality training set.

Data Collection

The first step in making a training set is choosing the right number of features for a particular dataset. The data should be consistent and have the least amount of missing values. In case a feature has 25% to 30% of missing values, then this feature should not be considered to be part of the training set.

However, there might be instances when such features might be closely related to another feature. In such a case, it’s advisable to impute and handle the missing values correctly to achieve desired results. At the end of the data collection step, you should clearly know how to handle preprocessing data.

Data Preprocessing

Once the data has been collected, we enter the data preprocessing stage. In this step, we collect the right data from the complete data set and build a training set. The steps to be followed here are:

  • Organize and Format: If the data is scattered across multiple files or sheets, it’s necessary to compile all this data to form a single dataset. This includes finding the relation between these datasets and preprocess to form a dataset of required dimensions.
  • Data Cleaning: Once all the scattered data is compiled to a single dataset, it’s important to handle the missing values. And, remove any unwanted characters from the dataset.
  • Feature extraction: The final step in the data preprocessing step deals with finalizing the right number of features required for the training set. One has to analyze and find out features that are absolutely important for the model to function accurately and select them for faster computations and low memory consumption.

Data Conversion

The data conversion stage consists of the following steps,

  • Scaling: Once the data is placed, it’s necessary to scale the data as per a definite value. For example, a bank application containing transaction amount being important, then it’s required to scale the data on transaction value to build a robust model.
  • Disintegration and composition: There might be certain features in the training data that can be better understood by the model when split. For example, time-series function, where days, month, year, hour, minutes, and seconds can be split for better processing.
  • Composition: While some features can be better utilized when disintegrated, other features can be better understood when combined with another.

This covers the necessary steps to be taken to build a high-quality training set for AI & ML models. While this might help you formulate a framework that helps you build training sets for your system, here’s how you can put these frameworks into action.

Dedicated In-house Team

One of the easiest way for you could be to hire an intern to help you with the task of collecting and preprocessing data. You can also set up a dedicated ops team to help with your training set requirements. While this method provides you with greater control over the quality, it isn’t scalable, and you’ll be forced to look for more efficient methods eventually.

Outsource Training Set Creation

If having an in-house team doesn’t cut it, it would be a smarter move to outsource it, right? Well, not entirely.

Outsourcing your training set creation has its own set of troubles. Right from training people to ensuring quality is maintained to making sure people aren’t cutting slack.

Training Data Solutions Providers

With AI & ML technologies continuing to grow and more companies joining the bandwagon to roll out AI-enabled tools. There are a plethora of companies that can help you with your AI/ML training dataset requirement. We at Bridged.co have served prominent enterprises delivering over 50 million datasets.

And that is everything you need to know about training data, and how to go about creating one that helps you build powerful, robust, and accurate systems.

How is big data generated

Why big data analytics is indispensable for today’s businesses.

Ours is the age of information technology. Progress in IT has been exponential in the 21st century, and one direct consequence is the amount of data generated, consumed, and transferred. There’s no denying that the next step in our technological advancement involves real-life implementations of artificial intelligence technology.

In fact, one could say we are already in the midst of it. And there’s a definitive link between the large amounts of digital information being produced — called Big Data when it exceeds the processing capabilities of traditional database tools — and how new machine learning techniques use that data to assist the development of AI.

However, this isn’t the only application of Big Data even if it has become the most promising. Big data analytics is now a heavily researched field which helps businesses uncover ground-breaking insights from the available data to make better and informed decisions. According to IDC, big data and analytics had market revenue of more than $150 billion worldwide in 2018.

What is the scale of data that we are dealing with today?

  • ·It is estimated that there will be 10 billion mobile devices in use by 2020. This is more than the entire world population, and this is not including laptops and desktops.
  • We make over 1 billion Google searches every day.
  • Around 300 billion emails are sent every day.
  • More than 230 million tweets are written every day.
  • More than 30 petabytes (that’s 1015 bytes) of user-generated data is stored, accessed and analyzed on Facebook.
  • On YouTube alone, 300 hours of video are uploaded every minute.
  • In just 5 years, the number of connected smart devices in the world will be more than 50 billion — all of which will collect, create, and share data.
Social media platforms have shot up human-generated data exponentially.

As an aside, in an attempt to impress the potential here, let me state that we analyze less than 1% of all available data. The numbers are staggering!

Before we get to classifying all this data, let us understand the three main characteristics of what makes big data big.

The 3 Vs of Big Data

Volume

Volume refers to the amount of data generated through various sources. On social media sites, for example, we have 2 billion Facebook users, 1 billion on YouTube, and 1 billion together on Instagram and Twitter. The massive quantities of data contributed by all these users in terms of images, videos, messages, posts, tweets, etc. have pushed data analysis away from the now incapable excel sheets, databases, and other traditional tools toward big data analytics.

Velocity

This is the speed at which data is being made available — the rate of transfer over servers and between users has increased to a point where it is impossible to control the information explosion. There is a need to address this with more equipped tools, and this comes under the realm of big data.

Variety

There are structured and unstructured data in all the content being generated. Pictures, videos, emails, tweets, posts, messages, etc. are unstructured. Sensor-collected data from the millions of connected devices is what you can call semi-structured while records maintained by businesses for transactions, storage, and analyzed unstructured information are part of structured data.

Classification of Big Data

With the amount of information that is available to us today, it is important to classify and understand the nature of different kinds of data and the requirements that go into the analysis for each.

Human Generated Data

Most human-generated data is unstructured. But this data has the potential to provide deep insights for heavy user-optimization. Product companies, customer service organizations, even political campaigns these days rely heavily on this type of random data to inform themselves of their audience and to target their marketing approach accordingly.

Machine Generated Data

Data created by various sensors, cameras, satellites, bio-informatic and health-care devices, audio and video analyzers, etc. combine to become the biggest source of data today. These can be extremely personalized in nature, or completely random. With the advent of internet-enabled smart devices, propagation of this data has become constant and omnipresent, providing user information with highly useful detail.

Data from Companies and Institutions

Records of finances, transactions, operations planning, demographic information, health-care records, etc. stored in relational databases are more structured and easily readable compared to disorganized online data. This data can be used to understand key performance indicators, estimate demands and shortage, prevalent factors, large-scale consumer mentality, and a lot more. This is the smallest portion of the data market but combined with consumer-centric analysis of unstructured data, can become a very powerful tool for businesses.

What we can do for you

Whether one is seeking a profit advantage or a market edge, carving a niche product or capturing crowd sentiment, developing self-driving cars or facial recognition apps, building a futuristic robot or a military drone, big data is available for all sectors to take their technology to the next level. Bridged is a place where such fruitful experiments in data are being utilized and we are endeavoring to provide assistance to companies who are willing to take advantage of this untapped but currently mandatory investment in big data.
