Detailed Description

template<bool Uniform = true>
class mlpack::ann::GlorotInitializationType< Uniform >

This class is used to initialize the weight matrix with the Glorot Initialization method.

The method is defined by

where is the number of neurons in the outgoing layer, represents the number of neurons in the ingoing layer. Here Normal Distribution may also be used if needed
