What are layers of transformers?

A transformer is like a super-smart helper who can understand and talk about things by looking at pieces of information all together.

Imagine you're building a tower with blocks. Each block represents a piece of a sentence, like the word "dog" or "runs." Now, think of the layers of transformers as different groups of helpers working on your tower.

The first group of helpers looks at each block and starts to understand what it means on its own, like knowing that "dog" is an animal and "runs" is something you do with your legs. This is like the first layer, where helpers get a basic understanding of every piece.

Then, the next groups of helpers look at how the blocks fit together, like seeing that "the dog runs" makes sense as a whole sentence. These layers help understand bigger ideas by combining smaller ones. More layers mean more helpers working on your tower, making it even smarter about what the full picture is.

Each layer is like a new team of helpers who take turns looking at your blocks and learning something new from them, helping the transformer become super good at understanding language!
