They are from open source Python projects. During last year (2018) a lot of great stuff happened in the field of Deep Learning. To minimize the dice coefficient loss function, we optimize the parameters in the neural network by using an adaptive moment optimizer called AdamW. Below is what I used for training ResNet-50, 120 training epochs is very much overkill for this exercise, but we just wanted to push our GPUs. For a workaround, you can use keras_applications module directly to import all ResNet, ResNetV2 and ResNeXt models, as given below. ) – Number of stages in a ResNet.
