When using Keras, it's possible to customize the SGD optimizer by directly instantiating the SGD class and using it while compiling the model: from keras.optimizers import SGD...sgd = SGD (lr=0.0001, momentum=0.8, nesterov=True)model.compile (optimizer=sgd, loss='categorical_crossentropy', … WebSets the gradients of all optimized torch.Tensor s to zero. Parameters: set_to_none ( bool) – instead of setting to zero, set the grads to None. This will in general have lower memory footprint, and can modestly improve performance. However, it changes certain behaviors. For example: 1. bradford thermoseal 733md
