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.

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.

How chatbots are redefining customer experience

Chatbots reliability and consistency in serving customers have changed the way the world created the customer experience. A company that regularly communicates with customers can experiment and improve using AI-based chatbots. Digital transformation can favor the customer service and experience. The world is moving fast and so are the technological advancements. If you intend to draw benefits from implementing the latest technology, there is no reason for further delay.

Why Customer Experience Is Important For Every Business?

Customer experience is a trophy that companies receive for something they do with pride. Companies focusing on improved customer experience know the worth of single positive feedback, share, comment and rebound effect it creates. New customer acquisition and maintenance of existing customers are crucial for market sustainability. Returning customers are solid proof of the experience you created for them. 

Customer loyalty is not achievable with marketing tactics it is a long-term investment in the customer relationship. The customers, who have a guarantee towards service or product, trust the companies. The companies in return continue to provide flawless service. Customer experience is a key feature in brand building. Attracting new customers is challenging and bringing back a lost customer is even tougher. 

Customer satisfaction has a direct impact on revenues and the company’s reputation. Thus, customer experience is of ultimate importance to every business.

How Has Customer Experience Changed Over The Years?

The customer experience has changed with the availability of internet and loads of information that influences the decisions. The power of researching about the product, services, and the competitor’s brands raises the overall expectations. The features, the price, functionality, use of advanced technology, and response from the company all such expectations have changed with the market. The launch of latest technology based affordable solutions is changing their demand.

Customer support is no more just issue resolution team; the general queries related to product, price, and availability are part of customer service. The location constraint; faced by customer care is removed by chatbots and it eases the process. It has changed the way the pre and post-sales interactions take place. Customer experience should be enjoyable, useful, and reliable. B2C businesses have a great opportunity to create a better customer experience.

What Are Chatbots?

Chatbots are AI-based conversational robots designed for the specific needs of the company and its services. The software executes automated tasks like communicating with users without any human control over the bot. These chat platforms either independent or via websites are effective through the internet. The chatbots developed with specific purposes as discussion and basic plus extended conversation with humans are just like instant messages.

The response to the queries is spontaneous and machine learning helps them process the requests. Chatbots can respond to the text and voice inquiries and perform the required actions. The knowledgebase helps chatbots to search for accurate response by combining information to communicate. Best examples of chatbots are Alexa from Amazon, Siri by Apple, Microsoft’s Cortana, and Google Home.

Companies like Pizza Hut, Uber, eBay, Lyft, Emirates, Bank of America, MongoDB, LeadPages, TechCrunch, and many more are already using chatbots to deliver a better experience to the customers.

Grand View Research Report says that the chatbot market globally is predicted to reach USD 1.2 billion in just ten years. The report says that the demand for intelligent virtual assistants is rising with automatic speech recognition and text to speech conversion. 

Why Do We Need Chatbots?

These instant messengers create a personal and real life-like experience. The speed and precision it brings to the customer service are securing chatbots position in businesses. The growth of the business is a factor that invites companies to get their own chatbots. 

Customization of messages is the next step for the improvement in chatbots. Repeating the same messages do not make sense hence learning from the customer behavior helps. Companies use chatbots by keeping their goals in mind; bringing relevance to the user journey, create intimate experiences, and engage with users.

Chatbots used uniquely for sending product updates, promotional messages, and product comparisons can deliver a better experience. We can collect user data, offer services, and replicate human interactions. The search of information is simplified, communicating can be easier, and personalization of information is possible too.

Chatbots take care of the basic level of communication. In case of inability to solve or in case of customer dissatisfaction; it passes to human handled customer service process.

Chatbots are available full time; they eliminate the waiting period for attendance by a customer care representative. They save money of companies spent on calls and customer care activities. You save on hiring and training costs of customer care executives.

Chatbots have no dependency on moods, feelings, interpretations and have no perception of who should behave how nor do they respond considering this. Chatbots can be effective at any given time and can do mundane tasks with the same precision every time without being bored.

Why Chatbots Are The Future Of Customer Service?

A survey by Business Insider suggests that 80% of the enterprises will use chatbots by the year 2020.

Businesses like banks, telecom, retail chains, e-commerce, and many industries use chatbots as virtual assistants for customer support. Initial training costs are higher but the inquiry management and response saves costs and time in the long run. It works on FAQs, the questions that are similar but framed differently by the users. The software allows the bot to explore the existing data about the user and the information stored on the topic. 

The ability to understand the queries, recognition of terminology, dialogues, and presentation of the query is machine learning. A chatbot can identify if it is a statement or problem, select a proper template for the response, cross-check with the user if the understanding of the question is correct. 

The data is collected from various sources by the bot; is cleaned, segregated, marked, and classified for reference. The data built from the customer service center e-mails, manual chats, training material, and call recordings are useful in improving customer experience. The dialogues that happen in this process are repetitive and this helps template creation and standardization of responses. The personal information from this data removed intelligently works in favor of companies. The intention is to extract the question-answer sets for further use.

The sequencing of data helps in organic search for the chatbot reducing the mistakes in understanding the questions. Chatbots can rectify typo errors and reframe the question-received input. Speak the language your audience uses not in terms of spoken language but the latest terms. Solve actual problems by asking relevant questions. Avoid missing opportunities by being available 24X7. A single chatbot can enter into multiple conversations that earlier needed a lot of employees.

Independently owned company or a large organization both can benefit from AI Chatbots. The companies with fewer resources or high frequency of customer conversations, in both the cases the chatbots, can serve more practically. Salesforce survey indicates that 64% of the agents can solve complex problems as AI Chatbots deal with the basic ones. 

The customer experience is changing and the expectations are rising with the immediate response in 42% cases and response in less than 5 mins in 36% cases. The speed with which chatbots communicates, businesses will certainly churn information fast to serve faster. (Salesforce.com)

How Are Chatbots Used In Business?

Businesses and customers can get a reliable solution from assistance AI-based chatbots provide.

  • Answering questions 
  • Redirecting to FAQs
  • Providing detailed explanations 
  • Resolving complaints 
  • Bill payments 
  • Flight or restaurant booking 
  • Schedule meetings
  • Purchase items 
  • Managing subscriptions
  • Creating a brand image

How Are AI Chatbots Bettering Customer Experience And How Data Is Enabling This?

Artificial intelligence involves machine learning. AI creates intelligent machines, and ML creates systems that can learn from experience. The eBay chatbot enables a user to chat using smartphone or Google Home and it can purchase a product at the lowest price with your instructions.

The data collected by asking questions on chat, collected from surveys or any brochures/e-books the user downloads are stored for future use. This data helps to communicate with the user in the future. The preferences of users are stored; this creates a strong rapport and good impression. The feeling that the company knows the customer is special. The customer can relate to how well a company deals with data. Latest offers during the chat process ease registration, with existing information. There is no need for the user to create logins.

The data AI chatbots uses increases customer engagement rate, build brand awareness, and creates a personalized experience. The amounts of e-mails read less or not opened, due to flooded inboxes. The chatbots allow us to share the same amount of information at a faster pace. Chatbots can send text, image, pdf, or message in any form. This restriction less communication introduces increased activities of marketing and promotion.

Chatbots are effective and soon may replace the search window on the websites. Creating a chatbot requires an understanding of the business as well as a target customer. If your customer base for the product is the 16-30 age group of chatbot can be a perfect solution. For the age group of 55-65 maybe it the design with voice command or connect calls would work better instead. The internet connectivity is the dependency for chatbot hence the drops in the internet or limited availability can be an obstacle in serving efficiently.

The AI data is useful for training purpose, analysis, and serving the customers better. The situations that arise occasionally and some that arise regularly are included in training the customer representatives with the accumulated data.

The Future Of Customer Experience And Chatbot

AI chatbots are preferred by most of the companies as it saves time, money, and efforts. About 46% of internet users in the US would choose live support instead of a chatbot as per a survey by usabilla.com.

Machine learning increases the accuracy level of chatbots. ML allows the system to learn from the data but AI helps in decision-making. ML finds the solution for a user but AI will find an optimal solution. The advanced systems can go beyond the general chat. They let the user know that they are speaking to a Chatbot. This can change the way they ask questions and the response received from the bot can become more acceptable.

According to the report by Global Market Insights, the market worth of chatbot will be $1.34 billion by the year 2024 and nearly 42% will be dedicated to customer service.

Connect the AI Chatbots created by you with facebook messenger, Alexa, Siri or any of the reliable bots to increase efficiency. Chatbots can help take actions that are interaction or information-based. The user can actually complete the task of purchase, shopping, booking from the same chat window. There remains no need for a user to search for other ways of completing the task. It saves time and effort of the users and the companies get faster conversions.

AI can hold conversations as humans do, these dialogues create comfort and trust for users to participate in product/service-related feedback or surveys. The simple and complex form of communication with the prospects and existing customers is levered by the chatbots.

Chatbots were in making since the 1950s but today they have shape conversations using the triggers as keywords. Chatbots are better listeners and thus provide better solutions to the problems. The designing of chatbot involves humans hence the customization is programmable. 

The chatbot applications are useful in customer service, social media marketing, and order processing. Sectors like BFSI, Media& Entertainment, Healthcare, Retail, and Travel & Tourism are widely using these solutions. The deployment of Chatbots can be on-premise or cloud, both opens easy ways of dealing with customers. 

With gradual development, the concerns of delay in response, irrelevant suggestions, sharing of inaccurate information, misunderstood requests, or unhelpful responses have become a checkpoint. This is not the failure of chatbot but the development stage, which can assure improvement by the involvement of AI companies. The continuous growth in AI technology is the commitment of experts for betterment of human life including the business aspects.

what is content moderation and why companies need it

Content Moderation refers to the practice of flagging user-generated submissions based on a set of guidelines in order to determine whether the submission can be used or not in the related media.  These rules decide what’s acceptable and what isn’t to promote the generation of content that falls within its conditions. This process represents the importance of curbing the output of inappropriate content which could harm the involved viewers. Unacceptable content is always removed based on their offensiveness, inappropriateness, or their lack of usability.

Why do we need content moderation?

In an era in which information online has the potential to cause havoc and influence young minds, there is a need to moderate the content which can be accessed by people belonging to a range of age-groups. For example, online communities which are commonly used by children need to be constantly monitored for suspicious and dangerous activities such as bullying, sexual grooming behavior, abusive language, etc. When content isn’t moderated carefully and effectively, the risk of the platform turning into a breeding ground for the content which falls outside the community’s guidelines increases.

Content moderation comes with a lot of benefits such as:

  • Protection of the brand and its users
    Having a team of content moderators allows the brand’s reputation to remain intact even if users upload undesirable content. It also protects the users from being the victims of content which could be termed abusive or inappropriate.
  • Understanding of viewers/users
    Pattern recognition is a common advantage of content moderation. This can be used by the content moderators to understand the type of users which access the platform they are governing. Promotions can be planned accordingly and marketing campaigns can be created based on such recognizable patterns and statistics.
  • Increase of traffic and search engine rankings
    Content generated by the community can help to fuel traffic because users would use other internet media to direct their potential audience to their online content. When such content is moderated, it attracts more traffic because it allows users to understand the type of content which they can expect on the platform/website. This can provide a big boost to the platform’s influence over internet users. Also, search engines thrive on this because of increased user interaction.

How do content moderation systems work?

Content moderation can work in a variety of methods and each of them holds their pros and cons. Based on the characteristics of the community, the content can be moderated in the following ways:

Pre-moderation

In this type of moderation, the users first upload their content after which a screening process takes place. Only once the content passes the platform’s guidelines is it allowed to be made public. This method allows the final public upload to be free from anything that’s undesirable or which could be deemed offensive by a majority of viewers.

The problem with pre-moderation is the fact that users could be left unsatisfied because it delays their content from going public. Another disadvantage is the high cost of operation involved in maintaining a team of moderators dedicated to ensuring top quality public content. If the number of user submissions increases, the workload of the moderators also increases and that could stall a significant portion of the content from going public.

If the quality of the content cannot be compromised under any circumstances, this method of moderation is extremely effective.

Post-moderation

This moderation technique is extremely useful when instant uploading and a quicker pace of public content generation is important. Content by the user will be displayed on the platform immediately after it is created, but it would still be screened by a content moderator after which it would either be allowed to remain or removed.

This method has the advantage of promoting real-time content and active conversations. Most people prefer their content online as soon as possible and post moderation allows this. In addition to this, any content which is inconsistent with the guidelines can be removed in a timely manner.

The flaws and disadvantages of this method include legal obligations of the website operator and difficulties for moderators to keep up with all the user content which has been uploaded. The number of views a piece of content receives can have an impact on the platform and if the content strays away from the platform’s guidelines, it can prove to be costly. Considering the fact that such hurdles exist, the content moderation and review process should be completed within a quick time slot.

Reactive moderation

In this case, users get to flag and react to the content which is displayed to them. If the members deem the content to be offensive or undesirable, they can react accordingly to it. This makes the members of the community responsible for reporting the content which they come across. A report button is usually present next to any public piece of content and users can use this option to flag anything which falls outside the community’s guidelines.

This system is extremely effective when it aids a pre-moderation or a post-moderation setup. It allows the platform to identify inappropriate content which the community moderators might’ve missed out on. It also reduces the burden on community moderators and theoretically, it allows the platform to dodge any claims of their responsibility for the user-uploaded content.

On the other hand, this style of moderation may not make sense if the quality of the content is extremely crucial to the reputation of the company. Interestingly, certain countries have laws which legally protect platforms that encourage/adopt reactive moderation.

AI Content Moderation

Community moderators can take the help of artificial intelligence inspired content moderation as a tool to implement the guidelines of the platform. Automated moderation is commonly used to block the occurrences of banned words and phrases. IP bans can also be established using such a tool.

Current shortcomings of content moderation

Content moderators are bestowed with the important responsibility of cleaning up all content which represents the worst which humanity has to offer. A lot of user-generated content is extremely harmful to the general public (especially children) and due to this, content moderation becomes the process which protects every platform’s community. Here are some of the shortcomings experienced by modern content moderation:

  • Content moderation comes with certain dangers such as continuously exposing content moderators to undesirable and inappropriate content. This can have a negative psychological impact but thankfully, companies have found a way to replace them with AI moderators. While this solves the earlier issue, it makes the moderation process more secretive.
  • Content moderation presently has its fair share of inconsistencies. For example, an AI content moderation setup can detect nudity better than hate speech, while the public could argue that the latter has more significant consequences. Also, in most platforms, profiles of public figures tend to be given more leniency compared to everyday users.
  • Content Moderation has been observed to have a disproportionately negative influence on members of marginalized communities. The rules surrounding what is offensive and what isn’t aren’t generally very clear on these platforms, and users can have their accounts banned temporarily or permanently if they are found to have indulged in such activity.
  • Continuing from the last statement, the appeals process in most platforms is broken. Users might end up getting banned for actions they could rightfully justify and it could take a long period of time before the ban is revoked. This is a special area in which content moderation has failed or needs to improve.

Conclusion

While the topic of content moderation comes with its achievements and failures, it completely makes sense for companies and platforms to invest in this. If the content moderation process is implemented in a manner which is scalable, it can allow the platform to become the source of a large volume of information, generated by its users. Not only can the platform enjoy the opportunity to publish a lot of content, but it can also be moderated to ensure the protection of its users from malicious and undesirable content.

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

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.

The need for quality training data | Blog | Bridged.o

What is training data? Where to find it? And how much do you need?

Artificial Intelligence is created primarily from exposure and experience. In order to teach a computer system a certain thought-action process for executing a task, it is fed a large amount of relevant data which, simply put, is a collection of correct examples of the desired process and result. This data is called Training Data, and the entire exercise is part of Machine Learning.

Artificial Intelligence tasks are more than just computing and storage or doing them faster and more efficiently. We said thought-action process because that is precisely what the computer is trying to learn: given basic parameters and objectives, it can understand rules, establish relationships, detect patterns, evaluate consequences, and identify the best course of action. But the success of the AI model depends on the quality, accuracy, and quantity of the training data that it feeds on.

The training data itself needs to be tailored for the end-result desired. This is where Bridged excels in delivering the best training data. Not only do we provide highly accurate datasets, but we also curate it as per the requirements of the project.

Below are a few examples of training data labeling that we provide to train different types of machine learning models:

How much training data does an AI model need?

The amount of training data one needs depends on several factors — the task you are trying to perform, the performance you want to achieve, the input features you have, the noise in the training data, the noise in your extracted features, the complexity of your model and so on. Although, as an unspoken rule, machine learning enthusiasts understand that larger the dataset, more fine-tuned the AI model will turn out to be.

Validation and Testing

After the model is fit using training data, it goes through evaluation steps to achieve the required accuracy.

Validation & testing of models | Blog | Bridged.co

Validation Dataset

This is the sample of data that is used to provide an unbiased evaluation of the model fit on the training dataset while tuning model hyper-parameters. The evaluation becomes more biased when the validation dataset is incorporated into the model configuration.

Test Dataset

In order to test the performance of models, they need to be challenged frequently. The test dataset provides an unbiased evaluation of the final model. The data in the test dataset is never used during training.

Importance of choosing the right training datasets

Considering the success or failure of the AI algorithm depends so much on the training data it learns from, building a quality dataset is of paramount importance. While there are public platforms for different sorts of training data, it is not prudent to use them for more than just generic purposes. With curated and carefully constructed training data, the likes of which are provided by Bridged, machine learning models can quickly and accurately scale toward their desired goals.

Understanding the Machine Learning technology that is propelling the future

Any computing system fundamentally works on the basic concepts of input and output. Whether it is a rudimentary calculator, our all-requirements-met smartphone, a NASA supercomputer predicting the effects of events occurring thousands of light-years away, or a robot-like J.A.R.V.I.S. helping us defend the planet, it’s always a response to a stimulus — much like how we humans operate — and the algorithms which we create teach the process for the same. The specifications of the processing tools determine how accurate, quick, and advanced the output information can be.

Computer Vision is the process of computer systems and robots responding to visual inputs — most commonly images and videos. To put it in a very simple manner, computer vision advances the input (output) steps by reading (reporting) information at the same visual level as a person and therefore removing the need for translation into machine language (vice versa). Naturally, computer vision techniques have the potential for a higher level of understanding and application in the human world.

While computer vision techniques have been around since the 1960s, it wasn’t till recently that they picked up the pace to become very powerful tools. Advancements in Machine Learning, as well as increasingly capable storage and computational tools, have enabled the rise in the stock of Computer Vision methods.

What follows is also an explanation of how Artificial Intelligence is born.

Understanding Images

Machines interpret images as a collection of individual pixels, with each colored pixel being a combination of three different numbers. The total number of pixels is called the image resolution, and higher resolutions become bigger sizes (storage size). Any algorithm which tries to process images needs to be capable of crunching large numbers, which is why the progress in this field is tangential to advancement in computational ability.

Understanding images | Blog | Bridged.co

The building blocks of Computer Vision are the following two:

Object Detection

Object Identification

As is evident from the names, they stand for figuring out distinct objects in images (Detection) and recognizing objects with specific names (Identification).

These techniques are implemented through several methods, with algorithms of increasing complexity providing increasingly advanced results.

Training Data

The previous section explains the architecture behind a computer’s understanding of images. Before a computer can perform the required output function, it is trained to predict such results based on data that is known to be relevant and at the same time accurate — this is called Training Data. An algorithm is a set of guidelines that defines the process by which a computer achieves the output — the closer the output is to the expected result, the better the algorithm. This training forms what is called Machine Learning.

This article is not going to delve into the details of Machine Learning (or Deep Learning, Neural Networks, etc.) algorithms and tools — basically, they are the programming techniques that work through the Training Data. Rather, we will proceed now to elaborate on the tools that are used to prepare the Training Data required for such an algorithm to feed on — this is where Bridged’s expertise comes into the picture.

Image Annotation

For a computer to understand images, the training data needs to be labeled and presented in a language that the computer would eventually learn and implement by itself — thus becoming artificially intelligent.

The labeling methods used to generate usable training data are called Annotation techniques, or for Computer Vision, Image Annotation. Each of these methods uses a different type of labeling, usable for various end-goals.

At Bridged AI, as reliable players for artificial intelligence and machine learning training data, we offer a range of image annotation services, few of which are listed below:

Applications of Computer Vision

It would not be an exaggeration to say computer vision is driving modern technology like no other. It 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 — and they are increasing by the day.

Facial Recognition
