WebAug 28, 2024 · Exploding gradients can be avoided in general by careful configuration of the network model, such as choice of small learning rate, scaled target variables, and a standard loss function. Nevertheless, exploding gradients may still be an issue with recurrent networks with a large number of input time steps.
