PHP マニュアル: Creates the training data struct from a user supplied function

説明

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.

パラメータ

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.

戻り値

成功した場合にニューラルネットワークトレーニングリソース、エラー時に false を返します。

例

例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
}
?>
