Hiding Node Title on the Front Page

How do you unset the node title on the front page?
In Omega 7.x-3.x, the can usually pre-process the the page through template.php and use something similar to this:

function theme_preprocess_page(&$vars) {
	if ($vars['is_front'] == 'TRUE') {
		$vars['title_hidden'] = 1;
	}
}

However, in Omega 7.x-4.x there is no longer a "$vars['title_hidden']" when trying to pre-process the page. The following suggestion does not seem to work in either the template.php file or the page.preprocess.inc files:

function theme_alpha_preprocess_page(&$vars) {
  // Hide the node title on the front page
  if($vars['is_front']) {
    $vars['title'] = '';
  }
}

Thanks in advance!
