WebFeb 8, 2024 · Normalized Xavier Weight Initialization. The normalized xavier initialization method is calculated as a random number with a uniform probability distribution (U) between the range -(sqrt(6)/sqrt(n + m)) and sqrt(6)/sqrt(n + m), where n us the number of inputs to the node (e.g. number of nodes in the previous layer) and m is the number of … WebAn initializer is just a PyTorch function. Here we implement a proxy class that allows us to register them and supply any additional function arguments (for example, the `mean` and `std` of a normal initializer) as named arguments to the constructor.
