fann_init_weights - Initialize the weights using Widrow + Nguyen's algorithm

SYNOPSIS

       bool fann_init_weights (resource  $ann, resource  $train_data)

DESCRIPTION

	Initialize the weights using Widrow + Nguyen's algorithm.

	This  function behaves similarly to fann_randomize_weights(3). It will use the algorithm developed by Derrick Nguyen and Bernard Widrow to
       set the weights in such a way as to speed up training. This technique is not always successful, and in some cases  can  be  less  efficient
       than a purely random initialization.

	The  algorithm	requires  access  to  the range of the input data (for example largest and smallest input), and therefore accepts a second
       argument, data, which is the training data that will be used to train the network.

PARAMETERS

	      o $ann
		-Neural network resource.

	      o $train_data
		-Neural network training data resource.

RETURN VALUES

       Returns TRUE on success, or FALSE otherwise.
