WebJul 26, 2024 · Exploding gradients are a problem when large error gradients accumulate and result in very large updates to neural network model weights during training. A gradient calculates the direction... WebJul 18, 2024 · When the gradients vanish toward 0 for the lower layers, these layers train very slowly, or not at all. The ReLU activation function can help prevent vanishing gradients. Exploding Gradients. If the weights in a network are very large, then the gradients for the lower layers involve products of many large terms. WebSep 2, 2024 · Gradient vanishing and exploding depend mostly on the following: too much multiplication in combination with too small values (gradient vanishing) or too large values (gradient exploding).
