摘要
在数据挖掘中,预测性模型是一个重要的方面。文中提出一个基于N阶转移概率的数据挖掘规则。给出了基本模型和算法,并评估了该算法的复杂性和优缺点。根据该算法,结合序列树提出了一个改进算法。
: Prognostic Model plays a critical role in Data Mining .A rule of DataMining which is based on n-rank transfer probability is presented in this paper.This paper introduces the basic model and the algorithm of the rule which is then evaluated.An advanced model based on this rule is introduced later with the sequence tree.
