"WebThere are two factors that affect the magnitude of gradients - the weights and the activation functions (or more precisely, their derivatives) that the gradient passes through. If either of these factors is smaller than 1, then the gradients may vanish in time; if larger than 1, then exploding might happen. " - How gru solve vanishing gradient problem

As the name 'exploding' implies, during training, it causes the model's parameter to grow so large so that even a very tiny amount change in the input can cause a great update in later layers' output. We can spot the issue by simply observing the value of layer weights.

Web25 feb. 2024 · The vanishing gradient problem is caused by the derivative of the activation function used to create the neural network. The simplest solution to the problem is to replace the activation function of the network. Instead of sigmoid, use an activation function such as ReLU.
