want to transform them layer after layer into sort of a a higher order representation of that same sequence and for that you build these layers out of nodes and you have as many nodes usually as you have tokens in the sequence and the next set of so each token is represented by a vector at the beginning and each layer transforms this sequence as i said into sort of a higher level representation so you want the vector of this token right here um to be a better representation than the vector was right here and you do that by incorporating
