| Abstract(in English) | In pattern recognition, feature selection is used for reducing the measurement cost of features or for improving the performance of classifiers of both. Especially, removing of features with no discriminative information is effective for improving the precision of estimated parameters of parametric classifiers. Many feature selection algorithms choose a feature subset that is useful for all classes in common. However, a best feature subset for separating one group of classes from another group of classes depends on the two groups. In this study, we investigate the basic effectiveness of an idea such that feature subsets are chosen depending of groups of classes and a classifer system is built as a decition tree in which nodes have those different feature subsets. |
