The attention mechanism … WebThere are two mechanisms of attention that can be found in the TensorFlow framework, which are implemented as Layer Attention (a.k.a. Luong-style attention) and Additive Attention (a.k.a. Bahdanau-style attention). In this article, I’m going to focus on explaining the two different attention mechanisms.

WebEdit. Additive Attention, also known as Bahdanau Attention, uses a one-hidden layer feed-forward network to calculate the attention alignment score: f a t t ( h i, s j) = v a T tanh ( W a [ h i; s j]) where v a and W a are learned attention parameters. Here h refers to the hidden states for the encoder, and s is the hidden states for the decoder.
