$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.
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:
The function should return an associative array with keys input and output and two array values of input and output.
Returns a train data resource on success, or FALSE
on error.
Example #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
}
