WebAug 20, 2024 · The mask is simply to ensure that the encoder doesn't pay any attention to padding tokens. Here is the formula for the masked scaled dot product attention: A t t e n t i o n ( Q, K, V, M) = s o f t m a x ( Q K T d k M) V. Softmax outputs a probability distribution. By setting the mask vector M to a value close to negative infinity where we have ...

The padding mask should have shape [95, 20], not [20, 95]. This assumes that your batch size is 95 and the sequence length is 20, but if that is the other way around, you would have to transpose the src instead. bous internationalWebJan 27, 2024 · First section.
