The paper discusses the properties of an attribute selection criterion for building rough set reducts based on discernibility matrix and compares it with Entropy and Gini index used for building decision trees. It has been shown theoretically and experimentally that Entropy and Gini index work better if the reduct is later used for prediction of previously unseen cases, and the criterion based ...

In order to explore the influence of green credit on optimization and rationalization industrial structure in China, based relevant data balance, interest expenditure six high-energy-consuming industries, China from 2007–2019, paper first measured index by methods entropy weight Theil index. Then, coupling model was adopted study degree coordination between them, regression employed further coe...

Abstract This paper is devoted to the study of properties entropy as a function Hurst index, which corresponds fractional Gaussian noise. Since vector depends on determinant covariance matrix, and behavior this index rather difficult analytically at high dimensions, we also consider simple alternative functionals, whose behavior, one hand, mimics and, other not study. Asymptotic normalized (so ...
