This paper aims to provide additional insights into the differences between RNNs and Gated Units in order to explain the superior perfomance of gated recurrent units. It is argued, that Gated Units are easier to optimize not because they solve the vanishing gradient problem, but because they ...
Specifically, the values of the error gradient are checked against a threshold value and clipped or set to that threshold value if the error gradient exceeds the threshold. To some extent, the exploding gradient problem can be mitigated by gradient clipping (thresholding the values of the gradient...

Understanding the exploding gradient problem, 2012. Articles Why is it a problem to have exploding gradients in a neural net (especially in an RNN)? How does LSTM help prevent the vanishing (and exploding) gradient problem in a recurrent neural network?
The gates allow information to flow from inputs at any previous time steps to the end of the sequence more easily, partially addressing the vanishing gradient problem. 特殊的网络结构: special neural architectures, such as hierarchical RNNs (El Hihi & Bengio, 1996), recursive neural networks (...
These activation functions work much like a step or ReLU do, and we may use either function for activation in a regular network layer. For the most part, we will treat an LSTM as a black box, and all you need to remember is that LSTMs overcome the gradient problem of RNN and can ...
This post has discussed what exploding gradients are and why they happen. In order to encounter this effect, we discussed a technique known as Gradient clipping and saw how this technique can solve the problem both theoretically and practically....
