The softmax function is an activation function that turns numbers into probabilities which sum to one. The softmax function outputs a vector that represents the probability distributions of a list of outcomes.

Floating Point and Softmax The softmax function normalizes a vector so its entries are positive and sum to 1. This is useful for creating a probability distribution across the vector, so it is commonly used as …

softmax 只有一个值为 1 的元素，其他都为 0 的话，反向传播的梯度会变为 0, 也就是所谓的梯度消失。 下面分别证明这 4 点。
