WebDec 30, 2024 · Without delving too deep into the internals of pytorch, I can offer a simplistic answer: Recall that when initializing optimizer you explicitly tell it what parameters (tensors) of the model it should be updating. The gradients are "stored" by the tensors themselves (they have a grad and a requires_grad attributes) once you call backward() on the loss. . … WebMar 14, 2024 · If you stack more LSTM layers, just keep propagating the errors further down through the respective gates until you reach the input layer. For a slightly more intuitive explanation, if you look at Fig. 2.1 in the dissertation, you can assume that in a multi-layered LSTM the IN in fact includes the OUT of the preceding LSTM layer. Edit
