WebEdit. Dot-Product Attention is an attention mechanism where the alignment score function is calculated as: f a t t ( h i, s j) = h i T s j. It is equivalent to multiplicative attention (without a trainable weight matrix, assuming this is instead an identity matrix). Here h refers to the hidden states for the encoder, and s is the hidden states ...
