Witryna29 mar 2016 · Hence: N * var (w i) = 1 var (w i) = 1/N. There we go! We arrived at the Xavier initialization formula. We need to pick the weights from a Gaussian distribution with zero mean and a variance of 1/N, where N specifies the number of input neurons. This is how it’s implemented in the Caffe library. Witrynadef pca_weights_init (self, data): """Initializes the weights to span the first two principal components. This initialization doesn't depend on random processes and: makes the training process converge faster. It is strongly reccomended to normalize the data before initializing: the weights and use the same normalization for the training data. """
