Clip gradients if necessary

WebClip gradient norms¶ Another good training practice is to clip gradient norms. Even if you set a high threshold, it can stop your model from diverging, even when it gets very high losses. While in MLPs not strictly necessary, RNNs, Transformers, and likelihood models can often benefit from gradient norm clipping. WebGradient clipping is one of the two ways to tackle exploding gradients. The other method is gradient scaling. In gradient clipping, we set a threshold value and if the gradient is more than that then it is clipped. In gradient …
