Web说到 layer 比较少，其实我是想说，orthogonal initialization，个人认为对于 LSTM （deep, high-dimensitional, non-convex）比较有效的原因是，（1）可以很方便地减缓 gradient vanishing/exploding problem 和 activation functions 的 saturation。 因为 orthogonal matrix 的所有 vectors 都是 orthonormal 的，也就是不仅 orthogonal，还 magnitude 为 1. 这 … WebIn a multilayer LSTM, the input x^ { (l)}_t xt(l) of the l l -th layer ( l >= 2 l >= 2) is the hidden state h^ { (l-1)}_t ht(l−1) of the previous layer multiplied by dropout \delta^ { (l-1)}_t δt(l−1) where each \delta^ { (l-1)}_t δt(l−1) is a Bernoulli random variable which is 0 0 with probability dropout.
