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…

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…

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…

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

Thanks for your amazing job.
i make a custom dataset. but my training is wrong. my loss is 0.
so i want to ask for dataset.
Do i normalized Object Size Range by image width and height?
And …

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…
