FINDING RARE CLASSES ACTIVE LEARNING WITH GENERATIVE
AND DISCRIMINATIVE MODELS
ABSTRACT:
Discovering rare categories and classifying new instances of them is an important data mining
issue in many fields but fully supervised learning of a rare class classifier is prohibitively costly
in labeling effort. There has therefore been increasing interest both in active discovery: to
identify new classes quickly, and active learning: to train classifier with minimal supervision.
These goals occur together in practice and are intrinsically related because examples of each
class are required to train a classifier. Nevertheless, very few studies have tried to optimize them
together, meaning that data mining for rare classes in new domains makes inefficient use of
human supervision. Developing active learning algorithms to optimize both rare class discovery
and classification simultaneously is challenging because discovery and classification have
conflicting requirements in query criteria.
In this paper we address these issues with two contributions: a unified active learning model to
jointly discover new categories and learn to classify them by adapting query criteria online; and a
classifier combination algorithm that switches generative and discriminative classifiers as
learning progresses. Extensive evaluation on a batch of standard UCI and vision datasets
demonstrates the superiority of this approach over existing methods.
