WebThe two most commonly used attention functions are additive attention , and dot-product (multiplicative) attention.Dot-product attention is identical to our algorithm, except for the scaling factor of \(\frac{1}{\sqrt{d_k}}\).Additive attention computes the compatibility function using a feed-forward network with a single hidden layer.
