摘要
引入基于粗糙集理论的属性约简算法分析了《中国震例》一书中记载的众多复杂的地震异常指标,通过约简去掉其中无关紧要的指标,保留一些彼此独立的关键核心指标,为地震预测研究提供更客观、更全面、更合理的数据源。
The complicated earthquake anomaly indexes recorded in ＂Earthquake Cases in China＂ are analyzed by using attribute reduction arithmetic based on rough set in this paper. Some inessential indexes are deleted by attribute reduction, and some key and self independent indexes are reserved, which can provide more objective, complete and reasonable data for earthquake forecast research.
