Abstract

Partially specified data are commonplace in many practical applications of machine learning where different instances are described at different levels of precision relative to an attribute value taxonomy (AVT). This paper describes AVT-NBL -- a variant of the Naive Bayes Learning algorithm that effectively exploits user-supplied attribute value taxonomies to construct compact and accurate Naive Bayes classifiers from partially specified data. Our experiments with several data sets and AVTs show that AVT-NBL yields classifiers that are substantially more accurate and more compact than those obtained using the standard Naive Bayes learner.
