WebSep 7, 2024 · Although LSTMs tend to not suffer from the vanishing gradient problem, they can have exploding gradients. Thus we enforced a hard constraint on the norm of the gradient [10,25] by scaling it when its norm exceeded a threshold. … So I would assume that LSTMs can also suffer from exploding gradients. Laura_Montalvo: WebIn order to speed up training process and seek global optimum for better performance, more and more learning rate schedulers have been proposed. ...
