Speech Title: Multi-class learning problems based on error-correcting output codes

Abstract: The multi-class classification problem is one of the important problems in machine learning. The common method to solve a multi-class classification problem is to decompose it into multiple binary problems. Dietterich and Bakiri in 1995 introduced the error-correcting output codes(ECOC) for this problem. The simplest decoding method, Hamming decoding, was employed to obtain a multi-class decision. In this presentation, we overview various ECOC methods and describe our recent work on ECOC based on Hadamard matrices.
