A few questions about the implementation

Hey, I understand most of what you did on Classifier.php. However, I have a few questions here.

Line 121:
$probability = ((1 * 0.5) + ($totalTokenCount * $probability)) / (1 + $totalTokenCount);

Why are you adding 0.5 to the result of ($totalTokenCount * $probability)'s division by (1 + $totalTokenCount)?

Great package, thanks!

I think it's best described here: http://burakkanber.com/blog/machine-learning-naive-bayes-1/ (see the paragraph "The Code: Guessing")
