Shared attention vector

Webb19 nov. 2024 · By letting the decoder have an attention mechanism, we relieve the encoder from the burden of having to encode all information in the source sentence into a fixed-length vector. With this new approach, the information can be spread throughout the sequence of annotations, which can be selectively retrieved by the decoder accordingly.” … Webb18 okt. 2024 · Attention is just a way to look at the entire sequence at once, irrespective of the position of the sequence that is being encoded or decoded. It was born as a way to enable seq2seq architectures to not rely on hacks like memory vectors, instead use attention as a way to lookup the original sequence as needed. Transformers proved that …

Webb15 mars 2024 · The attention mechanism is located between the encoder and the decoder, its input is composed of the encoder’s output vectors h1, h2, h3, h4 and the states of the decoder s0, s1, s2, s3, the attention’s output is a sequence of vectors called context vectors denoted by c1, c2, c3, c4. The context vectors WebbThe attention layer consists of two steps: (1) computing the attention vector b → using the attention mechanism and (2) the reduction over the values using the attention vector b →. Attention mechanism is a fancy word for the attention equation. Consider our example above. We’ll use a 3-dimensional embedding for our words WebbThe Attention class takes vector groups as input, and then computes the attention scores between and via the AttentionScore function. After normalization by softmax, it computes the weights sum of the vectors in to get the attention vectors. This is analogous to the query, key, and value in multihead attention in Section 6.4.1. energy-related products
