摘要翻译：
特征选择是高维数据分析和分类中的一个重要问题。传统的特征选择方法集中在基于冗余准则的特征检测上，使用学习和特征搜索方案。相比之下，我们提出了一种基于特征在类之间的区分能力来识别选择特征的必要性的方法。属性的特征与特征比较所产生的类间和类内距离之间的重叠面积被用作特征区分能力的度量。在由选择阈值定义的公差程度内具有最低重叠面积的模式中的一组最近属性被选择来表示最佳可用的可识别特征。本文报告了利用所提出的特征选择方案和最近邻分类器对模式分类问题进行识别的最新结果。这些结果是用具有高维特征向量的基准数据库在涉及图像和微阵列数据的问题中报告的。

英文摘要：
  Feature selection is an important problem in high-dimensional data analysis and classification. Conventional feature selection approaches focus on detecting the features based on a redundancy criterion using learning and feature searching schemes. In contrast, we present an approach that identifies the need to select features based on their discriminatory ability among classes. Area of overlap between inter-class and intra-class distances resulting from feature to feature comparison of an attribute is used as a measure of discriminatory ability of the feature. A set of nearest attributes in a pattern having the lowest area of overlap within a degree of tolerance defined by a selection threshold is selected to represent the best available discriminable features. State of the art recognition results are reported for pattern classification problems by using the proposed feature selection scheme with the nearest neighbour classifier. These results are reported with benchmark databases having high dimensional feature vectors in the problems involving images and micro array data.
