Webb21 mars 2024 · 11. There seem to be two ways of initializing embedding layers in Pytorch 1.0 using an uniform distribution. For example you have an embedding layer: self.in_embed = nn.Embedding (n_vocab, n_embed) And you want to initialize its weights with an uniform distribution. The first way you can get this done is: … Webb1 nov. 2024 · 在深度学习中,神经网络的权重初始化方法(weight initialization)对模型的收敛速度和性能有着至关重要的影响。模型的训练,简而言之,就是对权重参数W的不 …

First of all, there is a difference between the weights of a LSTM (the usual parameter set of a ANN), which are by default also initialized by the Glorot or also known as the Xavier initializer (as mentioned in the question). A different aspect is the cell state and the state of the initial recurrent input to the LSTM.
