Weboretical results. We show that orthogonal initialization can speed up training in the large learning rate and depth regime when the hyper-parameters are set to achieve a linear regime in nonlinear activation. 2 Related Work [Hu et al., 2024]’s investigation of orthogonal initialization in linear networks provided a rigorous proof that drawing WebWhen a module is created, its learnable parameters are initialized according to a default initialization scheme associated with the module type. For example, the weight parameter for a torch.nn.Linear module is initialized from a uniform (-1/sqrt (in_features), 1/sqrt (in_features)) distribution.

Default: "matrix_exp" if the matrix is square or complex, "householder" otherwise. … WebJul 20, 2016 · 2 Answers. Sorted by: 12. Normally, you would set the initial states to zero, but the network is going to learn to adapt to that initial state. The following article suggests learning the initial hidden states or using random noise. Basically, if your data includes many short sequences, then training the initial state can accelerate learning. pherial neuropathy bananas
