WebApr 23, 2024 · So I implement the focal loss ( Focal Loss for Dense Object Detection) with pytorch==1.0 and python==3.6.5. It works just the same as standard binary cross entropy loss, sometimes worse. Did I correctly implement it?

My implementation of label-smooth, amsoftmax, focal-loss, dual-focal-loss, triplet-loss, giou-loss, affinity-loss, pc_softmax_cross_entropy, and dice-loss(both generalized soft dice loss and batch soft dice loss). Maybe this is useful in my future work. Also tried to implement swish and mish activation functions.
WebJul 5, 2024 · Take-home message: compound loss functions are the most robust losses, especially for the highly imbalanced segmentation tasks. Some recent side evidence: the winner in MICCAI 2024 HECKTOR Challenge used DiceFocal loss; the winner and runner-up in MICCAI 2024 ADAM Challenge used DiceTopK loss.
