http://juditacs.github.io/2024/12/27/masked-attention.html WebSep 27, 2024 · Masking plays an important role in the transformer. It serves two purposes: In the encoder and decoder: To zero attention outputs wherever there is just padding in the input sentences. In the decoder: To prevent the decoder ‘peaking’ ahead at the rest of the translated sentence when predicting the next word.
