摘　　要：研究怎样利用以前挖掘所用的支持度、置信度参数信息,来估计当前挖掘的最佳支持度和最佳置信度的牛顿插值算法.首先研究牛顿插值能否用于自动确定支持度/置信度阈值,最后结合实例给出了牛顿插值法用于自动确定支持度/置信度阈值的方法,并验证了该方法的正确性与有效性.In this paper, we mainly study how to use the technology of interpolation to determine the threshold of support/confidence automatically. First, we study whether the technology of Newton interpolation can be used to determine the threshold of support/confidence automatically. Then we explain the method of how to use Newton interpolation formula to determine the threshold of support/confidence automatically in the task of mining association rules. And finally we give some detailed experimental examples to verify and demonstrate the correctness and usefulness of our theory and methods.
