WebFeb 3, 2024 · After a short research, I came to the conclusion that in my particular case, a Hybrid loss with _lambda_ = 0.2, _alpha_ = 0.5, _beta_ = 0.5 would not be much better than a single Dice loss or a single Tversky loss. Neither IoU (intersection over union) nor the standard accuracy metric are much better with Hybrid loss. WebNov 27, 2024 · Y is the ground truth. So, Dice coefficient is 2 times The area of Overlap divided by the total number of pixels in both the images. It can be written as: where: TP is True Positives. FP is False Positives; and. FN is False Negatives. Dice coefficient is very similar to Jaccard’s Index. But it double-counts the intersection (TP).
