Any idea if there is a default setting in the mahout implementation of naive bayes that has a threshold below which it does trigger? And would explain it not classifying anything?
..yes, I'll dig around in the code if I need to - but if you know off the top of your head... :) Take care, -stu ________________________________ From: Ted Dunning <[email protected]> To: [email protected]; Stuart Smith <[email protected]> Sent: Saturday, January 28, 2012 12:36 PM Subject: Re: Diagnosing naive bayes results It always tells you the most likely category, but you can redefine the output to only trigger if the most likely category really dominates the results. With two categories, this is reasonable. For a dozen it is much more debatable. This works with the SGD classifiers as well and I have seen this used in a multi-level classifier.
