Multi-agent Based Multi-knowledge Acquisition Method for Rough Set
The key problem in knowledge acquisition algorithm is how to deal with large-scale datasets and extract small number of compact rules.In recent years,several approaches to distributed data mining have been developed,but only a few of them benefit rough set based knowledge acquisition methods.This paper is intended to combine multiagent technology into rough set based knowledge acquisition method.We briefly review the multi-knowledge acquisition algorithm,and propose a novel approach of distributed multi-knowledge acquisition method.Information system is decomposed into sub-systems by independent partition attribute set.Agent based knowledge acquisition tasks depend on universes of sub-systems,and the agent-oriented implementation is discussed.The main advantage of the method is that it is efficient on large-scale datasets and avoids generating excessive rules.Finally,the capabilities of our method are demonstrated on several datasets and results show that rules acquired are compact,having classification accuracy comparable to state-of-the-art methods.
