As you can see this is not the same as computing the dice score of all the batch together.
WebNov 10, 2024 · Hi, I want to implement a dice loss for multi-class segmentation, my solution requires to encode the target tensor with one-hot encoding because I am working on a multi label problem. If you have a better solution than this, please feel free to share it. This loss function needs to be differentiable in order to do backprop.
