中文摘要：
特征选择（也称作属性选择）是简化数据表达形式，降低存储要求，提高分类精度和效率的重要途径。实际中遇到的大量的数据集包含着不完整数据。对于不完整数据，构造选择性分类器同样也可以降低存储要求，提高分类精度和效率。因此，对用于不完整数据的选择性分类器的研究是一项重要的研究课题。有鉴于此，提出了一种用于不完整数据的选择性贝叶斯分类器。在12个标准的不完整数据集上的实验结果表明，给出的选择性分类器不仅分类准确率显著高于非常有效地用于不完整数据的RBC分类器，而且分类性能更加稳定。
英文摘要：
Feature selection is an important policy to simplify data,reduce necessary memory and improve the accuracy and efficiency of classification.Data are often incomplete because of various kinds of reasons.For incomplete data,methods of constructing selective classifiers can also reduce necessary memory and improve the accuracy and efficiency of classification.So developing selective classifiers for incomplete data is an important problem.In this paper a method of constructing selective Bayes classifiers from incomplete data is presented.Experiments on twelve benchmark incomplete data sets show that not only is the classification accuracy of the selective classifier proposed much higher than that of the very efficient RBC classifier,but also its performance is more robust.
