fann_create_train_from_callback — Creates the training data struct from a user supplied function
$num_data
,$num_input
,$num_output
,$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_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 setnum_input
- The number of inputs per training datanum_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.
Retorna um resource de dados de treinamento em caso de sucesso ou false
em caso de erro.
Exemplo #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
}
?>

Esta função só estará disponível se a extensão fann tiver sido compilada usando a biblioteca libfann >= 2.2.
