-*- Mode: Text -*- AI-Calibrate version 1.0 ========================= AI::Calibrate - Perl module for producing probabilities from classifier scores In AI, classifiers usually return some sort of an instance score with their classifications. These scores can be used as probabilities in various calculations, but first they need to be calibrated. Naive Bayes, for example, is a very useful classifier, but the scores it produces are usually "bunched" around 0 and 1, making these scores poor probability estimates. Support vector machines have a similar problem. Both classifier types should be calibrated before their scores are used as probability estimates. This module calibrates a classifier using the Pool Adjacent Violators algorithm. INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES No other modules are required.
