| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | There have been studies of multi-class classification by combining multiple binary classifiers within the framework of error-correcting output coding. In these methods, the original multi-class classification problem is decomposed to multiple binary classification problems by using the code matrix prepared in advance. In this report, we propose a new method of using parts of a code matrix ``hierarchically''. We apply this method to various classification problems including synthetic datasets and datasets from UCI repository and results show that the proposed method is superior or comparative to other multi-class classification methods such as the Hamming decoding and the multi-class SVM. |
