WebThe pytorch RNN tutorial uses for p in net.parameters (): p.data.add_ (p.grad.data, alpha = -learning_rate) as optimizer. Does anyone know the difference between doing that or doing the classical optimizer.step (), once an optimizer has been defined explicitly? WebNov 7, 2024 · My optimizer needs w (current parameter vector), g (its corresponding gradient vector), f (its corresponding loss value) and… as inputs. This optimizer needs many computations with w, g, f inside to give w = w + p, p is a optimal vector that my optimizer has to compute it by which I can update my w.
