Rough Sets Theory and Its Application
Xiaoxue Song · 2005
Rough sets theory is a new mathematical tool to deal with uncertainty. It has been widely used in the area of ANN, machine learning,data mining, pattern recognition, fault diagnostics, etc. This paper introduces the basie concepts for rough set theory, including equivalent relation, upper\lower approximation and reduction, and some applications of rough set theory in areas like ANN, machine learning、 data mining etc are also discussed.
