WebFeb 10, 2024 · One compelling reason for using cross-entropy over dice-coefficient or the similar IoU metric is that the gradients are nicer. The gradients of cross-entropy wrt the logits is something like p − t, where p is the softmax outputs and t is the target. WebAug 27, 2024 · Recent research from 2024 into this area has shown that it is possible to optimize statistics in the precision/recall family like precision-at-fixed-recall, etc. by use of new proxy loss functions. The authors reported relative improvement for the chosen metrics using the new proxy losses vs. the baseline loss functions.

We observe that the reconstruction loss can naturally be the metric of the difficulty of the pre-training task. Therefore, we introduce an auxiliary loss predictor, predicting patch-wise losses first and deciding where to mask next.
