The derivative of the ReLU activation function is always 1 or 0, and together with the gradient shortcut pathway provided by residual connections in ResNet, these are the two key innovations for addressing vanishing gradients.

VerifiedThe vanishing gradient problem can be addressed by replacing activation functions (e.g., substituting ReLU for sigmoid), using residual connections, or adjusting the network architecture.81% similarUnverifiedReLU is currently the most popular activation function; it sets negative values to zero and leaves positive values unchanged, is computationally efficient, and effectively alleviates the vanishing gradient problem.73% similarUnverifiedResidual connections (ResNet), Batch Normalization, and the ReLU activation function are all architectural innovations developed to mitigate the vanishing/exploding gradient problem72% similarUnverifiedHandwired's documentation states that the comparison operation returns the derivative of a step function, which is zero everywhere except in gaps narrower than one grid step.72% similarUnverifiedResidual connections add each submodule's input directly to its output (output = F(x) + x), alleviating the vanishing gradient problem in deep networks64% similar
