标题： A note on the separability index

摘要： 在区分来自不同类别的对象时，这些类别越可分离，可以使用的分类器就越不需要复杂的计算和结构。因此，人们寻求一种能够快速捕捉类别之间这种可分离性概念的度量，同时具有直观地解释它所量化内容的能力。先前提出的可分离性度量——可分离性指数（SI）已被证明能够很好地直观反映类别可分离性。 本文简要指出该度量的局限性，并通过将其与另一种形式的可分离性度量相结合，提出了一种微小的改进，后者捕获了可分离性指数未涵盖的量。 显示英文摘要

摘要： In discriminating between objects from different classes, the more separable these classes are the less computationally expensive and complex a classifier can be used. One thus seeks a measure that can quickly capture this separability concept between classes whilst having an intuitive interpretation on what it is quantifying. A previously proposed separability measure, the separability index (SI) has been shown to intuitively capture the class separability property very well. This short note highlights the limitations of this measure and proposes a slight variation to it by combining it with another form of separability measure that captures a quantity not covered by the Separability Index.
