generateWeightsHeNormal: He normal weight initialization

Description

This function is used to generate random weights and biases using He normal weight initialization as described in He et al., http://arxiv.org/abs/1502.01852.

Usage

generateWeightsHeNormal(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.
