摘要
结合国内外的最新研究成果,提出了一种运用动态约简算法挖掘出大型数据库中稳定的分类规则的有效方法,可以对不断变化的数据库中新出现的对象进行分类,最后通过对其时间复杂度的分析证明了算法的高效性.
According to the most recent investigation results at home and abroad,a valid method to mine stable classification rules out of a large database is presented by applying dynamic reduction algorithm.This method can be used to classify new object which emerges during database updating.Finally,the high efficiency of the algorithm is verified through the analysis of the time complexity.
