Extended Bayesian Classifiers
For some years, I have been intrigued with the naive Bayesian
classifier, an algorithm for supervised learning that stores
a single probabilistic summary for each class and that assumes
conditional independence of the attributes given the class. Despite
these simpiifying assumptions, in many domains naive Bayes gives
results as good or better than much more sophisticated approaches
to induction.
In addition to analyses of naive Bayes' behavior, my colleagues
(Stephanie Sage and George John) and I have extended the basic
algorithm along a number of fronts, but striving to keep the
representational ability (and thus the inductive bias) within
reasonable bounds. This constrasts with much of the recent work
on learning with unrestricted Bayesian networks. Our studies
have led to the publications shown below.
