WebSep 25, 2024 · CrossEntropyLoss (which would better be called “CategoricalCrossEntropyWithLogitsLoss”) is essentially the same as BCEWithLogitsLoss, but requires making some small modifications to your network and your ground-truth labels that add a small amount of unnecessary redundancy to your network. Best. K. Frank 1 … WebThe cross entropy loss is 0.74, and MSE loss is 0.08. If we change the predicted probabilities to: [0.4, 0.6, 0, 0], the cross-entropy loss is 1.32, and MSE loss 0.12. As expected, the cross-entropy loss is higher in the 2nd case because the predicted probability is lower for the true label.
