Self attention softmax
Web总结一下就是 Softmax(A) 的分布会和d有关。因此 A 中每一个元素除以 \sqrt{d_k} 后，方差又变为1。这使得 Softmax(A) 的分布“陡峭”程度与d解耦，从而使得训练过程中梯度值保 …

WebMy answer is that sigmoid makes more sense in problems where the attention weights should be equal for those features that should clearly be included in the context vector. Softmax does not have such saturation property and therefore is not the best choice. 1.
