/**
* Apply multiplicative 1-centered Gaussian noise.
* As it is a regularization layer, it is only active at training time.
*
* When you use this layer as the first layer of a model, you need to provide the argument
* inputShape (a Single Shape, does not include the batch dimension).
*
* @param p Double, drop probability (as with 'Dropout').
* The multiplicative noise will have standard deviation 'sqrt(p/(1-p))'.
* @param inputShape A Single Shape, does not include the batch dimension.
* @tparam T Numeric type of parameter(e.g. weight, bias). Only support float/double now.
