APPROXIMATION CLASSIFIED PRECISION AND QUALITY BASED ON GENERAL RELATION ROUGH SET
摘要
Abstract
In approximation space ( U, R ) determined by equivalence relation R, the approximate classification accuracy expresses the percentage the correct decision occupies among all possible decisions made, and the approximate classification quality indicates the percentage the applied knowledge R precisely belongs to the objects of known classification. In this article these two mentioned concepts are extended to the generalised approximation space which is determined by general (binary) relation. By introducing the concept of solitary set, the metric formulae are given, and their rationalities are attested with an example at the end.关键词
