WebSep 7, 2024 · In Sequence to Sequence Learning with Neural Networks (which might be considered a bit old by now) the authors claim: Although LSTMs tend to not suffer from … WebGradient clipping is a technique that prevents the gradients from becoming too large or too small during training. This can help to prevent the training from diverging or getting stuck in poor local minima. Gradient clipping is particularly useful in training recurrent neural networks (RNNs) which are known to be sensitive to large gradients.
