WebJul 13, 2024 · The gradient we want to compute here is indeed: 1 if input > 0 and 0 if inputs <= 0. The nice thing is that inputs <= 0 <=> relu (inputs) = 0. So we can actually compute the gradient based on the result with grad_input [result == 0] = 0 (or with <=, that would give the same result as result >=0). 1 Like singleroc (Qin) May 6, 2024, 1:15am #8 Web2 days ago · The vanishing gradient problem occurs when gradients of the loss function approach zero in deep neural networks, making them difficult to train.
