NAME

6       AI::Categorizer::Learner::Guesser - Simple guessing based on class
7       probabilities
8

SYNOPSIS

10         use AI::Categorizer::Learner::Guesser;
11
12         # Here $k is an AI::Categorizer::KnowledgeSet object
13
14         my $l = new AI::Categorizer::Learner::Guesser;
15         $l->train(knowledge_set => $k);
16         $l->save_state('filename');
17
18         ... time passes ...
19
20         $l = AI::Categorizer::Learner->restore_state('filename');
21         my $c = new AI::Categorizer::Collection::Files( path => ... );
22         while (my $document = $c->next) {
23           my $hypothesis = $l->categorize($document);
24           print "Best assigned category: ", $hypothesis->best_category, "\n";
25           print "All assigned categories: ", join(', ', $hypothesis->categories), "\n";
26         }

DESCRIPTION

29       This implements a simple category guesser that makes assignments based
30       solely on the prior probabilities of categories.  For instance, if 5%
31       of the training documents belong to a certain category, then the
32       probability of any test document being assigned to that category is
33       0.05.  This can be useful for providing baseline scores to compare with
34       other more sophisticated algorithms.
35
36       See AI::Categorizer for a complete description of the interface.

METHODS

39       This class inherits from the "AI::Categorizer::Learner" class, so all
40       of its methods are available.
