May 02, 2019 · num = pred.size(0) What is num?I guess it is the size of mini-batch, the number of training examples, or the number of classes. If it is the size of mini-batch or the number of training examples, you can calculate per-example dice coefficients by using sum(dim=1) instead of sum().

https://stackoverflow.com/questions/47084179
I am trying to train a network for multiclass segmentation and I want to use dice coefficient (See this) as loss function instead of cross entropy.. You can have a look at the formula here (where S is segmentation and G is ground truth.). One naive simple solution is to take an average of the dice coefficient of each class and use that for loss function. . This approach would not …
