Currently, the two types of bounding box regression loss are ℓ n … Web10 feb. 2024 · 48. One compelling reason for using cross-entropy over dice-coefficient or the similar IoU metric is that the gradients are nicer. The gradients of cross-entropy wrt the logits is something like p − t, where p is the softmax outputs and t is the target. Meanwhile, if we try to write the dice coefficient in a differentiable form: 2 p t p 2 + t ... fluid power control blackburn https://turnersmobilefitness.com
