Focal Loss + Label Smoothing - PyTorch Forums

WebLabel Smoothing is a regularization technique that introduces noise for the labels. This accounts for the fact that datasets may have mistakes in them, so maximizing the likelihood of log p ( y ∣ x) directly can be harmful. Assume for a small constant ϵ, the training set label y is correct with probability 1 − ϵ and incorrect otherwise. Webdistribution (one-hot label) and outputs of model, and the second part corresponds to a virtual teacher model which provides a uniform distribution to teach the model. For KD, by combining the teacher’s soft targets with the one-hot ground-truth label, we find that KD is a learned LSR where the smoothing distribution of KD is from a teacher is break my stride copyrighted https://colonialfunding.net

Web1 Answer. Sorted by: 39. The answer is yes, but you have to define it the right way. Cross entropy is defined on probability distributions, not on single values. For discrete distributions p and q, it's: H ( p, q) = − ∑ y p ( y) log q ( y) When the cross entropy loss is used with 'hard' class labels, what this really amounts to is treating ...
