JaccardLoss (mode, classes = None, log_loss = False, from_logits = True, smooth = 0.0, eps = 1e-07) [source] ¶ Implementation of Jaccard loss for image segmentation task. It supports binary, multiclass and multilabel cases. Parameters. mode – Loss mode ‘binary’, ‘multiclass’ or ‘multilabel’

I found this somewhere and adapted it for me. I'll post the link if I can find it again. Sorry in case this was a dublicate.

Note that PyTorch optimizers minimize a loss. In this: case, we would like to maximize the jaccard loss so we: return the negated jaccard loss. Args: true: a tensor of shape [B, H, W] or [B, 1, H, W]. logits: a tensor of shape [B, C, H, W]. Corresponds to: the raw output or logits of the model. eps: added to the denominator for numerical ...

Adapted from an awesome repo with pytorch utils https://github.com/BloodAxe/pytorch-toolbelt ... Implementation of Jaccard loss for image segmentation task.

Jan 15, 2018 · Say your outputs are of shape [32, 256, 256] # 32 is the minibatch size and 256x256 is the image's height and width, and the labels are also the same shape.. Then you can use sklearn's jaccard_similarity_score after some reshaping.
