I’m still in the process of learning, so I’m not sure my implementation is right. This was used with only one output class but it can be scaled easily. 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:. For details on how to use it, see its docstring.
