Let's learn about Transformers :

Transformer Concepts in Coding:
A Transformer is a type of artificial intelligence model used to understand and generate sequences of information, especially language. Transformers are the technology behind many modern AI systems, including large language models. Instead of processing words strictly one at a time, Transformers can look at many parts of a sentence at once and determine how they relate to each other.

 Simple Example

Consider:

"The cat sat on the mat because it was tired.” To understand what “it” refers to, an AI needs to connect it with the cat. Transformers are designed to identify relationships like this using a mechanism called attention.

Attention

Attention is the heart of the Transformer. It allows the model to determine which tokens are important when interpreting another token.

For example:

"The dog chased the ball because it was moving."

The model can use attention to determine which earlier words are relevant to understanding “it.”

The basic idea is:

"When I'm processing this word, which other words should I pay attention to?”
