WebThe normal vs uniform init seem to be rather unclear in fact. If we refer solely on the Glorot's and He's initializations papers, they both use a similar theoritical analysis: they find a good variance for the distribution from which the initial parameters are drawn. This variance is adapted to the activation function used and is derived without explicitly considering the …
