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), … WitrynaThis module provides common neural network layer initializers, consistent with definitions used in Keras and Sonnet. An initializer is a function that takes three arguments: (key, shape, dtype) and returns an array with dimensions shape and data type dtype.

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 ...
