fann_create_train_from_callback

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.

num_dataThe number of training data

num_inputThe number of inputs per training data

num_outputThe number of ouputs per training data

user_function The user supplied function with following parameters:

 `num``num_input``num_output`


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

Voorbeeld: 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
}
?>
