# small multinomial Naive Bayes text classification probabilities

When applying multinomial Naive Bayes text classification I get very small probabilities(around 10e-48) so there's no way for me to know which classes are valid predictions and which ones are not. I'd the probabilities to be in the interval [0,1] so I can exclude classes in the prediction with say a score of 0.5 or less. How do I go about doing this? This is what I've implemented:

• I think your probabilities are split up among all possible outputs. If you add them all together, do they come out to 1? Order them by value and you have your predictions – Zakk Diaz Jul 17 '18 at 18:30
