基于趋势概念格的决策规则挖掘

Decision rules extraction based on trend concept lattice

通过分析动态信息系统基于时间序列的对象变化特征,提出对象相关的趋势概念格概念,基于决策规则提取的目标,提出相应的建格算法和决策规则提取算法,并以股票走势预测为例,验证了算法的有效性。

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.
