(PECL fann >= 1.0.0)
fann_create_train_from_callback — Creates the training data struct from a user supplied function
説明
$num_data
, int $num_input
, int $num_output
, callable $user_function
)Creates the training data struct from a user supplied function. As the training data are numerable (data 1, data 2...), the user must write a function that receives the number of the training data set (input, output) and returns the set.
パラメータ
-
num_data -
The number of training data
-
num_input -
The number of inputs per training data
-
num_output -
The number of ouputs per training data
-
user_function -
The user supplied function with following parameters:
- num - The number of the training data set
- num_input - The number of inputs per training data
- num_output - The number of ouputs per training data
The function should return an associative array with keys input and output and two array values of input and output.
返り値
成功した場合にニューラルネットワークトレーニングリソース、エラー時に FALSE を返します。
例
例1 fann_create_train_from_callback() example
<?php
function create_train_callback($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
}
?>
