https://discuss.pytorch.org/t/self-attention-on-words-and-masking/5671
01.08.2017 · I have a simple model for text classification. It has an attention layer after an RNN, which computes a weighted average of the hidden states of the RNN. I sort each batch by length and use pack_padded_sequence in order to avoid computing the masked timesteps. The model works but i want to apply masking on the attention scores/weights. Here is my Layer: class …
