Batch Normalization and ReLU for solving Vanishing Gradients

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. Rectified Linear Units (ReLU) are activation functions that generate a ... WebThis problem could be solved if the local gradient managed to become 1. This can be achieved by using the identity function as its derivative would always be 1. So, the gradient would not decrease in value because the local gradient is 1.
