Shared attention vector

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.
