Decision rules extraction based on trend concept lattice
基于趋势概念格的决策规则挖掘

Through analyzing the transition feature of object based on time sequence in the dynamic information system, trend concept lattice related to the object was proposed. According to the goal of extracting decision rules, two corresponding algorithms were put forward, the former was used for constructing lattice and the later was used for extracting decision rule based on the decision lattice which was generated by the former. Finally, the two algorithms were used in stock forecasting to verify the validity of them.
