What are you trying to do? 
$trainset[scalar(@trainset)] = \@inputs;
$trainset[scalar(@trainset)] = \@outputs;

Is going to set the value to be \@outputs only (it will override).

So you should get 0 and 1 (the values of the outputs only) as your array elements.

Ok, nevermind, I'm thoroughly confused :)

I tested this and found the outputs to be the same except that the @trainset values are treated as strings. 

$VAR1 = [
          [
            '0',
            '0'
          ],
          [
            '0'
          ],
          [
            '0',
            '1'
          ],
          [
            '1'
          ]
        ];
$VAR1 = [
          [
            0,
            0
          ],
          [
            0
          ],
          [
            0,
            1
          ],
          [
            1
          ]
        ];
