Abstract

The Error Correcting Output Codes (ECOC) algorithm has played more and more important role in the artificial intelligence (AI) study and research fields in recent years due to its special properties and error correcting abilities. Various methods have been reported to improve its performance and classification accuracy. In this study, we developed a simplified ECOC encoding method to reduce the complexity in the encoding process and reduce its randomness in initializing the coding matrix. Furthermore, we also suggested a fuzzy mapping decoding (FMD) method used for the ECOC decoding process to improve its classification accuracy. By using this FMD, the classification accuracy can be improved up to 84% compared with the decoding method without using the FMD, which is 77%.
