摘要
实际应用中,信息系统的数据常常是动态变化的,动态属性约简是邻域系统中研究的重要内容之一。针对邻域系统中对象变化的动态属性约简问题,提出邻域系统中对象变化的动态属性约简算法。介绍邻域系统中的差异度概念;分析对象变化时差异度的变化机制。UCI数据集上的实验验证了所提算法的可行性。
In practical application,the data is often dynamic in information system,and dynamic attribute reduction is one of the important research contents in neighborhood system.Aiming at the problem of dynamic attribute reduction with object change in neighborhood system,we proposed the dynamic attribute reduction algorithm of object change in the neighborhood system.The concept of difference degree in neighborhood system was introduced.The change mechanism of the difference degree was analyzed when the object changed.Experiments on the UCI dataset demonstrate the feasibility of the proposed algorithm.
