WebAug 20, 2024 · With a multinomial cross-entropy loss function, this yields okay-ish results, especially considering the sparse amount of training data I´m working with, with mIoU of 0.44: When I replace this with my dice loss implementation, however, the networks predicts way less smaller segmentations, which is contrary to my understanding of its theory. WebIntersection over Union (IoU) is the most popular evaluation metric used in the object detection benchmarks. However, there is a gap between optimizing the commonly used distance losses for regressing the parameters of a bounding box and maximizing this metric value. The optimal objective for a metric is the metric itself. In the case of axis-aligned 2D …
