Recently, an interpretation of the whitened cosine similarity measure as a Bayes decision rule was proposed (C. Liu, "The Bayes Decision Rule Induced Similarity Measures,'' IEEE Trans. Pattern Analysis and Machine Intelligence, vol. 29, no. 6, pp. 1086-1090, June 2007. This communication makes the observation that some of the distributional assumptions made to derive this measure are very restrictive and, considered simultaneously, even inconsistent.
最近,有人提出将白化余弦相似度度量解释为一种贝叶斯决策规则(C. 刘,“由贝叶斯决策规则导出的相似度度量”,《IEEE 模式分析与机器智能汇刊》,第 29 卷,第 6 期,第 1086 - 1090 页,2007 年 6 月)。本通信指出,为推导该度量所做的一些分布假设非常具有限制性,并且同时考虑时甚至是不一致的。
