摘 要: 数据分类是数据挖掘领域中一个非常重要的研究课题,而判定树归纳分类是数据分类技术中最常用的方法之一,应用广泛。工程建设需要对工程用土进行分类定名,在土工试验中土的分类定名相当烦琐,而且土的用途或工程性质不同适用分类标准也不同,手工进行土质分类定名容易出错。将判定树归纳分类法应用于土质分类定名工作,介绍了判定树归纳算法,根据最高信息增益构建土质分类的预测模型,并给出了具体的数据分类实例。 Data classification is a very important subject in data mining. The decision tree induce classification is one of the most common methods of data classification techniques with extensive application. Soil classification is a demand of engineering. Soil classification in soil test is very troublesome. Moreover, if the use or engineering property of the soil is different, the suitable classification standard is different. The hand classification tends to make mistakes. The decision tree induce classification method is applied in soil classification. The algorithms of the decision tree induce classification is introduced and a prognosis model of classification by maximum information gain is built. A concrete data classification example is also given.
