WebMar 11, 2024 · The binary cross entropy loss function is applied to most pixel-level segmentation tasks. However, when the number of pixels on the target is much smaller than the number of pixels in the background, that is, the samples are highly unbalanced, and the loss function has the disadvantage of misleading the model to seriously bias the … WebFor a general covariance, cross-entropy would correspond to a squared Mahalanobis distance. For 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.
