Rough Data and Rough Data Law Recognition
S-rough sets (singular rough sets) theory wasproposed by improving Z.Pawlak rough sets theory. S-rough set has dynamic characteristics, since it isdefined by R -element equivalence class x which hasdynamic characteristic. The concept of rough data waspresented by employing S-rough sets, and rough datahas dynamic characteristic, furthermore, the roughdata law generation is given. Based on the conceptsabove, the generation theorem and the reversiontheorem of rough data law, the recognition principle ofrough data law, and the discernible theorem of roughdata law were given, finally the applications of roughdata law in risk investment system are presented.
