A New Algorithm Based on Variable Precision Rough Set to Deal With Noise Data in Data Mining
The noise data processing in data mining is a very important issue. In this paper a variable precision rough set model is proposed to deal with noise data. Based on variable precision rough set theory, we analyze the attribute significance from the point of dependence rate, and propose two kinds of heuristic algorithms; one computes core set firstly, then reduces the attributes; the other one abandons computation for a core and reduces attributes directly. Finally, we use an actual example which applies the second algorithm to verify it.
