WebRough set theory (RST) was proposed by Zdzistaw Pawlak (Pawlak,1982) as a methodology for data analysis using the notion of discernibility of objects based on their attribute values. The main advantage of using RST approach is that it does not need additional assumptions--like data distribution in statistical analysis. Besides, it provides efficient algorithms and …WebWanderlei Silva 424K views, 1.7K likes, 31 loves, 26 comments, 57 shares, Facebook Watch Videos from UFC Fight Pass: PRIDE 19: Wanderlei Silva vs Kiyoshi Tamura #PRIDENeverDie Access PRIDE Events...
