Gradient clipping max norm
WebSorted by: 4 torch.nn.utils.clip_grad_norm_ performs gradient clipping. It is used to mitigate the problem of exploding gradients, which is of particular concern for recurrent networks (which LSTMs are a type of). Further details can be found in the original paper.

Looking at each gradient would be quite unreasonable.

In terms of how to set max_grad_norm, you could play with it a bit to see how it affects your results. This is usually set to quite small number (I have seen 5 in several cases).
WebNov 3, 2024 · Why is norm clipping used instead of the alternatives? sgugger November 3, 2024, 1:53pm #2. It usually improves the training (and is pretty much always done in the fine-tuning scripts of research papers), which is why we use it by default. Norm clipping is the most commonly use, you can always try alternatives and see if it yields better results. WebFeb 24, 2024 · The rationale for this was to support both the old and new ways of specifying gradient clipping. The difference is that in the old way, gradient clipping is specified as max_grad_norm parameter of the fp32 optimizer, while in the new (and more intuitive way IMHO) gradient clipping is handled in the fp16 wrapper optimizer, such as here.In …
