Abstract

Abstract: The paper introduces the state of incomplete data as well as ICA’s and ViSOM’s characteristics，studies the method of incomplete data sets under the circumstances of that data remain dependent and non-Gaussian.Based on ICA and SOM，a model named IVS-IDH，is proposed in this paper.The proposed model can achieve the visualization of incomplete data sets based on SOM，so that it overcomes the remedy for handing of incomplete data proposed by Wang S.

Key words: incomplete data, Independent Component Analysis（ICA）, Self-Organizing Maps（SOM）, correlation, Gaussian distribution

摘要： 介绍了数据挖掘中不完整数据的研究现状及ICA与SOM的特点，提出了基于ICA与SOM的不完整数据的处理模型IVS-IDH，研究了数据之间存在相关关系且为非高斯分布时不完整数据的处理方法，在SOM基础上取得了不完整数据集的可视化分析结果，从而克服了Wang S提出的不完整数据处理方法的不足。

关键词: 不完整数据, ICA, SOM, 相关关系, 高斯分布
