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.
