fann_create_train_from_callback — Creates the training data struct from a user supplied function
$num_data
, int $num_input
, int $num_output
, collable $user_function
)Creates the training data struct from a user supplied function. As the training data are numerable (data 1, data 2...), the user must write a function that receives the number of the training data set (input, output) and returns the set.
num_dataThe number of training data
num_inputThe number of inputs per training data
num_outputThe number of ouputs per training data
user_functionThe user supplied function with following parameters:
The function should return an associative array with keys input and output and two array values of input and output.
Retourne une ressource de données d'entrainement en cas de succès, ou FALSE si une erreur survient.
Exemple #1 fann_create_train_from_callback() example
<?php
function create_train_callback($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
}
