(PECL fann >= 1.0.0)
Creates the training data struct from a user supplied function
resource fann_create_train_from_callback ( int $num_data, int $num_input, int $num_output, callable $user_function )
Creates the training data struct from a user supplied function. As the training data are numerable (data 1, data 2...), the user must write a function that receives the number of the training data set (input, output) and returns the set.
Parameters:
num_data
The number of training data
num_input
The number of inputs per training data
num_output
The number of ouputs per training data
user_function
The user supplied function with following parameters:
- num - The number of the training data set
- num_input - The number of inputs per training data
- num_output - The number of ouputs per training data
The function should return an associative array with keys input and output and two array values of input and output.
Returns:
Returns a train data resource on success, or FALSE
on error.
Examples:
fann_create_train_from_callback() example
<?php function create_train_callback($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 } ?>
