Iou-balanced loss
WebarXiv.org e-Print archive Web15 aug. 2024 · In this work, IoU-balanced loss functions that consist of IoU-balanced classification loss and IoU-balanced localization loss are proposed to solve the above problems. The IoU-balanced classification loss pays more attention to positive examples with high IoU and can enhance the correlation between classification and localization tasks.

Defaults to True. reduction (str, optional): The method used to reduce the loss into a scalar. Defaults to 'mean'. Options are "none", "mean" and "sum". loss_weight (float, optional): Weight of loss. Web10 feb. 2024 · 48. 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. Meanwhile, if we try to write the dice coefficient in a differentiable form: 2 p t p 2 + t ...

Web13 nov. 2024 · Further, we propose a novel gradient harmonizing mechanism (GHM) to be a hedging for the disharmonies. The philosophy behind GHM can be easily embedded into both classification loss function like cross-entropy (CE) and regression loss function like smooth-L_1 (SL_1) loss. To this end, two novel loss functions called GHM-C and …
