The Law Mining on Function Singular Rough Sets

Function singular rough sets (function s- rough sets) is defined by function relation equivalence class [u], Function s-rough sets has law characteristic, and a function is a law. Using function s-rough sets, this paper presents the research of law mining, it also presents the approach and application of law mining. Function S-rough sets is a new theory to discover the unknown law in systems. The result of this paper´s research can be applied in many application fields, for example, investment risk analysis, recognition of system status and so on. Function S-rough sets is a new research direction of the rough sets theory.
