Pytorch kl loss add cross entropy loss

WebFor an exponential distribution, the cross-entropy loss would look like f θ ( x) y − log f θ ( x), where y is continuous but non-negative. So yes, cross-entropy can be used for regression.

WebMar 6, 2024 · Machine learning classifiers often use the cross-entropy H [ p, q], where p is the true distribution (often a delta) and q is the predicted distribution over classes (or can at least be interpreted that way). Minimizing this is the same as minimizing the KL-divergence between the truth and the prediction, since H [ p, q] = D KL [ p q] + H [ p]
