generateWeightsGlorotNormal: Glorot normal weight initialization

Description

This function is used to generate random weights and biases using Glorot normal weight initialization as described in Glorot & Bengio, AISTATS 2010.

Usage

generateWeightsGlorotNormal(numUnits1, numUnits2,
  weights.mean = getParameter(".weights.mean", 0, ...), ...)

Arguments

numUnits1

Number of units in the lower layer.

numUnits2

Number of units in the upper layer.

weights.mean

mean parameter to the rnorm function.

...

Additional parameters, used for parameter resolution and passed to generateWeightsNormal.

Value

Weight matrix.
