WebNote that the entropy of a one-hot distribution is 0, so for one-hot vectors the KL = X-entropy. The reason they are separated in most libraries is because you can compute the X-entropy of a one hot vector slightly faster than the KL since you only need to compute the log-softmax of one of the logits.
