WebMar 20, 2024 · Scaled dot-product attention architecture. 首先说明一下我们的K、Q、V是什么: 在encoder的self-attention中,Q、K、V都来自同一个地方(相等),他们是上一层encoder的输出。 对于第一层encoder,它们就是word embedding和positional encoding相加得到的输入。 在decoder的self-attention中,Q、K、V都来自于同一个地方(相等),它 … WebSep 26, 2024 · You may note that the scaled dot-product attention can also apply a mask to the attention scores before feeding them into the softmax function. Since the word embeddings are zero-padded to a specific sequence length, a padding mask needs to be introduced in order to prevent the zero tokens from being processed along with the input …
