FANN_GET_CASCADE_NUM_CANDIDATES(3)					 1					FANN_GET_CASCADE_NUM_CANDIDATES(3)

fann_get_cascade_num_candidates - Returns the number of candidates used during training

SYNOPSIS

       int fann_get_cascade_num_candidates (resource  $ann)

DESCRIPTION

	The  number  of  candidates  used during training (calculated by multiplying fann_get_cascade_activation_functions_count(3), fann_get_cas-
       cade_activation_steepnesses_count(3) and fann_get_cascade_num_candidate_groups(3)).

	The actual candidates is defined by the fann_get_cascade_activation_functions(3)  and  fann_get_cascade_activation_steepnesses(3)  arrays.
       These arrays define the activation functions and activation steepnesses used for the candidate neurons. If there are 2 activation functions
       in the activation function array and 3 steepnesses in the steepness array, then there will be 2x3=6  different  candidates  which  will	be
       trained.  These	6  different candidates can be copied into several candidate groups, where the only difference between these groups is the
       initial weights. If the number of groups is set to 2, then the number of candidate neurons will be 2x3x2=12. The number of candidate groups
       is defined by fann_set_cascade_num_candidate_groups(3).

	The default number of candidates is 6x4x2 = 48

PARAMETERS

	      o $ann
		-Neural network resource.

RETURN VALUES

	The number of candidates used during training, or FALSE on error.

FANN_CREATE_TRAIN_FROM_CALLBACK(3)					 1					FANN_CREATE_TRAIN_FROM_CALLBACK(3)

fann_create_train_from_callback - Creates the training data struct from a user supplied function

SYNOPSIS

       resource fann_create_train_from_callback (int  $num_data, int  $num_input, int  $num_output, collable  $user_function)

DESCRIPTION

	Creates  the  training	data  struct  from a user supplied function. As the training data are numerable (data 1, data 2...), the user must
       write a function that receives the number of the training data set (input, output) and returns the set.

PARAMETERS

	      o $num_data
		- The number of training data

	      o $num_input
		- The number of inputs per training data

	      o $num_output
		- The number of ouputs per training data

	      o $user_function
		- The user supplied function with following parameters:

		     o num - The number of the training data set

		     o num_input - The number of inputs per training data

		     o num - The number of ouputs per training dataThe number of inputs per training data

	       The function should return an associative array with keys input and output and two array values of input and output.

RETURN VALUES

	Returns a train data resource on success, or FALSE on error.

EXAMPLES

       Example #1

	      fann_create_train_from_callback example

	      <?php
	      function create_train_callback($num_data, $num_input, $num_output) {
		  return array(
		      "input" => array_fill(0, $num_input, 1),
		      "output" => array_fill(0, $num_output, 1),
		  );
	      }

	      $num_data = 3;
	      $num_input = 2;
	      $num_output = 1;
	      $train_data = fann_create_train_from_callback($num_data, $num_input, $num_output, "create_train_callback");
	      if ($train_data) {
		  // Do something with $train_data
	      }
	      ?>
