VERSION

version 0.04

SYNOPSIS

            

              
              
my $result = $classifier->classify({bar => 3, blurp => 2});
# $result is an AI::NaiveBayes::Classification object
say $result->best_category;
my $predictors = $result->find_predictors;
            
          

DESCRIPTION

AI::NaiveBayes::Classification represents the result of a bayesian classification, produced by AI::NaiveBayes classifier.

METHODS

best_category()

Returns a string being a label that suits given document the best.

find_predictors()

This method returns the best_category(), as well as the list of all the predictors along with their influence on the best category selected. So the second value returned is a list of array references, where each one contains a string being a single feature and a number describing its influence on the result. So the second part of the result may look like this:
