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.

Web13 May 2024 · From reading Bahdanau's paper, nowhere states that the alignment score is based on the concatenation of the decoder state ( s i) and the hidden state ( h t ).
