| Abstract: | Rough Set Theory has an inherent ability of dealing with imprecise and incomplete information while in most cases it produces a large quantity of rules, thus reducing readability. On the contrary, expansion matrix theory canmerely handle precise and complete information while it is efficient to get formulas that cover as many positive examples as possible yet meanwhile kick away all negative ones. So we present a new data mining approach that combines rough set theory and expansion matrix theory in order to absorb merits of both while eliminate drawbacks of both. And we find it quite efficient to discover concise knowledge in databases. |
