Unit 5

Here is how to use Aiclass_NaiveBayes class:

require_once "library/Aiclass/NaiveBayes.php";
require_once "library/Aiclass/Exception.php";

$nb = new Aiclass_NaiveBayes();
$nb->addClass("ham", array("BEAUTIFUL SUMMER", "SECRET FRIEND"))
    ->addClass("spam", array("A SECRET LINK", "SECRET MONEY"))
    ->setSmoothingParameter(1)
    ->setPrecision(4);

// This gives you the exact probability for each class
$probabilities = $nb->getProbabilities();
echo $probabilities['spam'];

// This gives you the calculation's details for each class
$outputs = $nb->getOutputs();
echo '<pre>' . $outputs['spam'] . '</pre>';
