在两类模式识别问题中的特征的上下文中的评价表明，无论两个类的先验概率的值，现有的下限和上限之间的最大差异贝叶斯错误概率的Bhattacharyya系数约等于0.2071。
In the context evaluation of features in a two-class pattern recognition problem it is shown that, irrespective of the values of the a priori probabilities of the two classes, the maximum differences between the existing lower and upper bounds to Bayesian probability of error in terms of the Bhattacharyya coefficient is approximately equal to 0.2071.
