UnverifiedThe core pain point of traditional RNNs (including GRU and LSTM) is that historical information decays at an exponential rate during backpropagation, leading to vanishing gradients.73% similarUnverifiedBoth LSTM and GRU retain a structure that computes sequentially by time step, and therefore cannot be parallelized.70% similarUnverifiedLSTM通过门控机制维护隐藏状态处理序列数据，解决了简单RNN的梯度消失问题69% similarUnverifiedRNNs suffer from the long-range dependency problem: as sequences grow longer, early information tends to suffer vanishing gradients during backpropagation.60% similarUnverifiedCommon solutions for vanishing gradients include replacing sigmoid with ReLU and its variants, batch normalization, and residual connections (the core idea behind ResNet).59% similar
