An investigation of noise-tolerant relational concept learning algorithms Clifford A. Brunk and Michael J. Pazzani Department of Information and Computer Science University of California, Irvine Irvine, CA 92717 USA brunk@ics.uci.edu Abstract We discuss the types of noise that may occur in relational learning systems and describe two approaches to addressing noise in a relational concept learning algorithm. We then evaluate each approach experimentally.
