基于决策树的不完整数据的处理

Treatment of the Incomplete Data Based on the Decisive Tree

基于数据采集过程中常常存在一些不完整数据,以及不完整数据总是和样本空间中其他完整数据存在一定的相似性,提出了一种基于决策树的不完整数据的处理方法。在对不完整数据处理方法的比较、分析的基础上,采用一种有效的决策树方法对不完整数据处理。实例验证证明该决策树方法在不完整数据处理方面有很好的效果。

The incomplete data, came into being in the process of clara coliection, always have some similarities to the complete data in the sample space. This article presents a treatment of the incomplete data based on the decisive tree. On the base of the comparison and analyses of the treatment of the incomplete data, a useful decisive tree is used to deal with such data, and at last, it is testified by an experiment. The experiment shows that the decisive tree can achieve a good result in the treatment of the incomplete data.
