Web2 days ago · Solutions to the Vanishing Gradient Problem. An easy solution to avoid the vanishing gradient problem is by selecting the activation function wisely, taking into account factors such as the number of layers in the neural network. Prefer using activation functions like ReLU, ELU, etc. Use LSTM models (Long Short-Term Memory).
