Download scientific diagram | | The loss functions for the 16x16 D-UNet (red), ... While more epochs could be used, the loss function flattens after 70 ...

If I understand your question correctly - the "ground truth" mask is just a gray-scale image with values in range [0,255], ...

Furthermore, we have also introduced a new log-cosh dice loss function and compared its performance on NBFS skull-segmentation open source data- ...

Cross entropy is definitely the way to go. I don't know Keras but TF has this: https://www.tensorflow.org/api_docs/python/tf/nn/ ...

30.05.2019 · Hi Nikronic, Thanks for the links! However, None of these Unet implementation are using the pixel-weighted soft-max cross-entropy loss that is defined in the Unet paper (page 5).. I’ve tried to implement it myself using a modified version of this code to compute the weights which I multiply by the CrossEntropyLoss:. loss = …

10.08.2018 · If this is not possible, how would I modify the loss function (I'm aware of this post, however, just passing in the weights in to the loss function won't cut it, because the loss function is called separately for each class) ? Currently, I'm using the following loss function: def dice_coef(y_true, y_pred): smooth = 1.

Focal loss and mIoU are introduced as loss functions to tune the network parameters. Finally, we train the U-Net implemented in PyTorch to perform semantic ...

What kind of loss one would use in such an intrinsic image segmentation? Well, it is defined simply ... UNET with CrossEntropy Loss Function.
