| Abstract: | We mainly study the decision rule extraction based on local rough set model. Make improvement on the rule extraction based on classical rough set, we give the decision rule formula based on the local rough set model, and find its related theorems. Parameter value α, α∈(0,1］ is introduced into the rule extraction formula based on local rough, which makes the generalization ability and applicability of the rule extraction formula stronger. Three examples are given to illustrate the application of decision rule extraction in local rough set model. |
