Nettet6. jan. 2024 · Before the introduction of the Transformer model, the use of attention for neural machine translation was implemented by RNN-based encoder-decoder architectures. The Transformer model revolutionized the implementation of attention by dispensing with recurrence and convolutions and, alternatively, relying solely on a self … Nettet🎙️ Alfredo Canziani Attention. We introduce the concept of attention before talking about the Transformer architecture. There are two main types of attention: self attention vs. cross attention, within those categories, we can have hard vs. soft attention.. As we will later see, transformers are made up of attention modules, which are mappings …
