Artificial Intelligence (AI) has already been part of our everyday life. From virtual assistants to automated recommendation systems, AI uses various technologies that we use regularly.
AI tools like ChatGPT, Google Gemini, and GitHub Copilot have changed the way we obtain knowledge and perform tasks.
But have you ever thought about how these AI tools can provide you with answers within some seconds? Beneath the easy response is a series of complex calculations. In this blog, we will explore how AI chatbot works in step by step process-
Natural Language Processing(NLP)-
The first stage is for AI to comprehend what you are requesting. This understanding is interpreted with Natural Language Processing (NLP). NLP enables AI to understand human language, reading it and comprehending the meaning attached to human language.
Tokenization : AI breaks your input into small groups of tokens.
A token can be a word or part of a word.
For example, if you give input:
"Why is the sky blue?"
AI segments it into a tokens list like:
["Why", "is", "the", "sky", "blue", "?"]
Making tokens allows the computer to work with your text better.
Contextual Analysis: AI considers the context and attempts to understand the meaning. Words can have different meanings depending on the sentence.
For example, in our example sentence, “sky” is clearly referencing the sky above not a person named “Sky”. The AI uses its models to attempt to guess the correct meaning.
Contextual Reasoning-
After comprehending your query, AI relies on contextual reasoning to determine what type of response to generate. It uses the models like Transformers, which have been trained on massive amount of data.
Pattern Recognition: AI relies on its knowledge of patterns in language to predict sequential words. As in the example -
“Why is the sky blue?”
AI will know from patterns in its training that the answer will typically require a response talking about light, the atmosphere, and scattering.
Self-Attention Mechanism: This is what helps AI identify, out of all the words in the question, the most important to focus on as they generate a response. In “sky” and “blue” are the most important as key words in this example.
This self-attention mechanism can make sure that the focus of the reasoned response to the answer is given to the words that really matter in the question.
Creating Response
Once understanding the question, it starts to give an answer predicting one word at a time, choosing the most probable word based on the patterns it has learned. As an example, it could generate:
"The sky appears blue because sunlight is scattered by the air in the atmosphere, and blue light scatters more than other colors."
AI is also able to use these techniques to make the answer sound natural and fluid, so it doesn’t sound as if it is answering in a robotic way.
Safe and Accurate
AI performs a safety and quality check before providing a response to ensure that the generation is correct and appropriate.
Content Moderation: AI uses this type of algorithms to check if the generated response contains harmful, biased, or irrelevant information. This helps to ensure that any given response is factual, respectful, and appropriate for all users.
Fine-Tuning: AI uses user feedback and new data from the internet, to continuously improve the model. This is important for AI to stay relevant, find the best answer, and model contextual understanding. Together, these steps ensure every response is safe, reliable, and as easy to comprehend as possible.
Giving the Response
At last, AI gives the response to your device. Even though it appears just like talking with someone, AI conducts thousands of calculations in fractions of a second, including tokenization, pattern recognition, reasoning, and filtering.
