$num_data,int
$num_input,int
$num_output,callable
$user_function): resource
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.
Parameter-Liste
-
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
inputandoutputand two array values of input and output.
Rückgabewerte
Gibt bei Erfolg eine Ressource mit Trainingsdaten zurück,
ansonsten false im Fehlerfall.

Beispiel #1 fann_create_train_from_callback() example

"output" => array_fill(0, $num_output, 1),
);
}
$num_data = 3;
$num_input = 2;
$num_output = 1;
