【Abstract】 Based on the incremental algorithm,this paper proposes a new algorithm that can induce decision trees from the decreasing datasets.At the same time ,this paper also presents and testifies the three theorems that ensure the valid-ity of the decreasing algorithm.Furthermore,integrating the traditional incremental algorithm with decreasing algorithm,this paper proposes a dynamic algorithm of decision trees,which can extract rules of decision trees from the changeable datasets.The dynamic algorithm can promote the development and perfection of the On-Line Rules Extraction.更多还原
