WebbClearly, at initialization you now have a linear network because. ρ ( W l 0 x) = W l ′ σ ( x) − W l ′ σ ( − x) = W l ′ x. which is why we call this initalization LL (looks-linear). The LL-init can be "extended" easily to CNNs (see the cited paper for details). It does have the disadvantage of forcing you to change your architecture ...

WebbKaiming Initialization, or He Initialization, is an initialization method for neural networks that takes into account the non-linearity of activation functions, such as ReLU activations. A proper initialization method should avoid reducing or magnifying the magnitudes of input signals exponentially. Using a derivation they work out that the condition to stop this …

In his paper On weight initialization in deep neural networks, Siddharth Krishna Kumar identifies mathematically what the problem is with vanishing and exploding gradients and why He and Xavier (or Glorot) initialization do work against this problem. He argues as follows: Deep neural networks face the … Visa mer Before I can make my point with respect to the He and Xavier initializers and their relationships to activation functions, we must take a look at the individual ingredients of this blog first.
