AI总结:

本文通过统计模拟分析多变量对称不确定性(MSU)在混合特征下的行为,发现属性数、基数和样本大小影响MSU,并提出保持其高质量的条件,为降维提供新准则。

摘要:

本文通过统计模拟技术,在各种信息性与非信息性随机生成特征的混合下,分析了多变量对称不确定性(MSU)度量的行为。实验展示了属性数量、基数和样本大小如何影响MSU。我们发现了一个在上述三种因素的不同组合下保持MSU高质量的条件,为推动降维过程提供了新的有用准则。

英文摘要:

In this paper, we analyze the behavior of the multivariate symmetric uncertainty (MSU) measure through the use of statistical simulation techniques under various mixes of informative and non-informative randomly generated features. Experiments show how the number of attributes, their cardinalities, and the sample size affect the MSU. We discovered a condition that preserves good quality in the MSU under different combinations of these three factors, providing a new useful criterion to help drive the process of dimension reduction.
