WebThe transformer also leverages other techniques, such as residual connections, layer normalization, and feedforward networks, which help improve the stability and performance of the model. Such architectures are called transformers because they transform the input sequence into an output sequence using a series of transformer “blocks”. WebThen each of those "contextualized-meaning embeddings" are then put through the same 2 layer, fully connected feed-forward network - which has an output of the same size …
