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.

fann_train_on_file - Trains on an entire dataset, which is read from file, for a period of time

SYNOPSIS

       bool fann_train_on_file (resource  $ann, string	$filename, int	$max_epochs, int  $epochs_between_reports, float  $desired_error)

DESCRIPTION

	Trains on an entire dataset, which is read from file, for a period of time.

	This training uses the training algorithm chosen by fann_set_training_algorithm(3) and the parameters set for these training algorithms.

PARAMETERS

	      o $ann
		-Neural network resource.

	      o $filename
		- The file containing train data

	      o $max_epochs
		- The maximum number of epochs the training should continue

	      o $epochs_between_reports
		- The number of epochs between calling a user function. A value of zero means that user function is not called.

	      o $desired_error
		- The desired fann_get_MSE(3) or fann_get_bit_fail(3), depending on the stop function chosen by fann_set_train_stop_function(3)

RETURN VALUES

       Returns TRUE on success, or FALSE otherwise.
