什么是scaled dot-product attention? 什么是缩放点积注意力? - 知乎

WebEdit. Dot-Product Attention is an attention mechanism where the alignment score function is calculated as: f a t t ( h i, s j) = h i T s j. It is equivalent to multiplicative attention (without a trainable weight matrix, assuming this is instead an identity matrix). Here h refers to the hidden states for the encoder, and s is the hidden states ... WebScaled dot product attention attempts to automatically select the most optimal implementation based on the inputs. In order to provide more fine-grained control over what implementation is used, the following functions are provided for enabling and disabling implementations.
