摘要:

本文提出了一种新的相似性度量,用于一般任务,包括监督学习,这是代表的K-最近邻分类器(KNN)。所提出的相似性度量在特征空间的某些维度上对大的差异是不变的。数学上证明了该度量是一个度量。为了测试其在不同应用中的可行性,KNN使用所提出的度量对从许多真实数据集中选择的测试示例进行分类。实验结果表明,该距离度量方法是一种很有前途的KNN分类器距离度量方法,具有广泛的应用前景。

英文摘要:

This paper presents a new similarity measure to be used for general tasks including supervised learning, which is represented by the K-nearest neighbor classifier (KNN). The proposed similarity measure is invariant to large differences in some dimensions in the feature space. The proposed metric is proved mathematically to be a metric. To test its viability for different applications, the KNN used the proposed metric for classifying test examples chosen from a number of real datasets. Compared to some other well known metrics, the experimental results show that the proposed metric is a promising distance measure for the KNN classifier with strong potential for a wide range of applications.
