Cause the num of positive labels using center_on is much less than using in_bbox, I found classification scores are much lower when CENTER_POS_RADIOS = 1.5 than CENTER_POS_RADIOS = 3.0, should I set t…

Hello, I have gone through your paper 'End-to-End Cascade Network for 3D Brain Tumor Segmentation in MICCAI 2018 BraTS Challenge'. As you claimed focal loss implementation in the architecture, can you…

Greetings,
Jan, thank you so much for the package. It's amazing. I am working on implementing focal loss and it's the first loss function that I've designed so I am running into a few issues tha…

Should the focal loss not be applied per pixel? The reduction occurs when computing the crossentropy loss but shouldn't it occur at the very end?
criterion = nn.CrossEntropyLoss(weight=self.wei…

Hi, thank you for your useful repo about a lot of loss functions.
I had a problem about class imbalance problem in my project, but solved this problem by using this repo.
But, when using this repo…

@AlexeyAB You gave an implementation of focal loss in the yolo layer (6056b83#diff-180a7a56172e12a8b79e41ec95ae569dR121).
### Question 1
Is this the full code of focal loss for Yolo v3?
Accordin…

when i change softmaxwithloss to focal-loss, in the beginning of training, the loss becomes 87.3365.
When using softmaxwithloss, there is no such a problem.
Is the code still under the testing pha…

In losses.py, we're required to finish the part of Focal Loss from 107th line to 117th line.
`focal_weight = "?"`
`bce = "?"`
`cls_loss = focal_weight * bce`
However, I'm a little bit con…

I want to know how to use eqlv2 for dense object detection which uses focal loss for classification? Any ideas?
