Vanishing Gradients can be detected from the kernel weights distribution. All you have to look for is whether the weights are dying down to 0. If only 25% of your kernel weights are changing that does not imply a vanishing gradient, it might be a factor, but there can be a variety of reasons, such as poor data, loss function used to the ...

How do LSTM and GRU avoid to overcome the vanishing gradient problem?

WebThis means that the partial derivatives of the state of the GRU unit at t=100 are directly a function of its inputs at t=1. Or to reword, it means that the state of the GRU at t=100 … WebCompared to vanishing gradients, exploding gradients is more easy to realize. 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. hillcroft gas
