WebApplies the rectified linear unit activation function. With default values, this returns the standard ReLU activation: max(x, 0), the element-wise maximum of 0 and the input tensor. Modifying default parameters allows you to use non-zero thresholds, change the max value of the activation, and to use a non-zero multiple of the input for values below the threshold. 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 can chickens eat dry cat foodWeb2 days ago · The vanishing gradient problem occurs when gradients of the loss function approach zero in deep neural networks, making them difficult to train.
