Label smoothing torch

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. WebNLLLoss. class torch.nn.NLLLoss(weight=None, size_average=None, ignore_index=- 100, reduce=None, reduction='mean') [source] The negative log likelihood loss. It is useful to train a classification problem with C classes. If provided, the optional argument weight should be a 1D Tensor assigning weight to each of the classes.

WebApr 21, 2024 · new_image = t * image1 + (1-t) * image2. where t is a float between 0 and 1. Then the target we assign to that image is the same combination of the original targets: new_target = t * target1 + (1-t) * target2. assuming your targets are one-hot encoded (which isn't the case in pytorch usually). And that's as simple as this. WebAug 18, 2024 · Is there a label smoothing version for multi-label classification?
