Hi @eckelsjd,
Thank you for sharing, it is really helpful!
I was using a custom accuracy function which I found here: https://forums.fast.ai/t/create-databunch-with-multiple-segmentation-mask-as-label/53643/20
However, I think IoU provides more information for segmentation problems. I might use several metrics.
I’m not finished with the v2 lessons yet, but I do not think they’ve taken something like this metric into account. Also, the options for evaluation, such a confusion matrices, are not really there for segmentation purposes.
So thanks again!
