Witryna8 lut 2024 · The xavier initialization method is calculated as a random number with a uniform probability distribution (U) between the range - (1/sqrt (n)) and 1/sqrt (n), where n is the number of inputs to the node. weight = U [- (1/sqrt (n)), 1/sqrt (n)] We can implement this directly in Python.

Witryna26 sie 2024 · Xavier initialization assumes the input to have zero mean, but things change when we use a ReLU which sets all negative values to zero. Let's see what happens if we continue using Xavier initialization with ReLU WitrynaA flexible and efficient library for deep learning. Apache MXNet is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator.Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have …
WitrynaThis initializer is designed to keep the scale of the gradients roughly the same in all layers. In uniform distribution this ends up being the range: x = sqrt(6. / (in + out)); [-x, x] and for normal distribution a standard deviation of sqrt(2. / (in + out)) is used. Args: uniform: Whether to use uniform or normal distributed random ...
