Incremental rules extraction based on rough set theory
基于粗糙集理论的增量式规则获取

The incremental rules extraction is a focus problem of KDD.A novel rules extraction algorithm which is called "RDBRST"(Rule Derivation Based on Rough set and Search Tree) was proposed.It was one kind of width first heuristic search algorithms.The incremental rules were extracted and the current rule set was updated based on this algorithm.An example was given to illustrate the characteristics of this new incremental algorithm.
