What exactly does the forward function output in Pytorch?
stackoverflow.com › questions › 64987430Nov 24, 2020 · This example is taken verbatim from the PyTorch Documentation.Now I do have some background on Deep Learning in general and know that it should be obvious that the forward call represents a forward pass, passing through different layers and finally reaching the end, with 10 outputs in this case, then you take the output of the forward pass and compute the loss using the loss function one defined.
PyTorch - Wikipedia
https://en.wikipedia.org/wiki/PyTorchPyTorch uses a method called automatic differentiation. A recorder records what operations have performed, and then it replays it backward to compute the gradients. This method is especially powerful when building neural networks to save time on one epoch by calculating differentiation of the parameters at the forward pass. torch.optim is a module that implements various optimization algorithms used for building neur…
