Practice and graded self study.
Install a linux at home or among friends and
- learn basic commands. I used to have a starter list - ls, mv, cp, cd, mkdir, vi, who, ps, sed, grep, concept of PATH
- Next learn scripting (awk, and shell scripting),
- Then how to compile a c/c++ programme and download a tarball.
Having done this for about an year or two, you can begin to read up books on "Design of the Unix operating system".
OK

- The number of training data
o $num_input
- The number of inputs per training data
o $num_output
- The number of ouputs per training data
o $user_function
- The user supplied function with following parameters:
o num - The number of the training data set
o num_input - The number of inputs per training data
o num - The number of ouputs per training dataThe number of inputs per training data
The function should return an associative array with keys input and output and two array values of input and output.
RETURN VALUES
Returns a train data resource on success, or FALSE on error.
EXAMPLES
Example #1
fann_create_train_from_callback example
<?php
function create_train_callback($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
}
?>
