This paper is a study on decision tree classification algorithms , which mainly includes two parts 本文主要对决策树分类算法展开研究,主要包含两个内容: 1
The traditional decision tree category methods ( such as : id3 , c4 . 5 ) are effective on small data sets 摘要传统的决策树分类方法(如id3和c4 . 5 )对于相对小的数据集是很有效的。
So bp neural network is used to classify the stored food insects primarily . the result shows our method is effective 实验表明,利用bp神经网络分类器作初级分类器的树分类结构进行分类,是一种行之有效的方法。
This new idea can be applied for any other algorithm . thus it produces a new way for improving classifying algorithm accuracy 这种方法也可以应用于其它的决策树构造算法中,为提高决策树分类算法的准确性提供了新的途径。
Many different techniques have been proposed for classification , including statistical approaches , neural networks , decision tree algorithm and rough sets 现有数据分类方法有统计方法、决策树分类方法、神经网络方法、粗集法等。
Secondly , decision tree classification model and logistic regression model are performed to rock mass quality assessment , based on sas / enterprise miner 应用sas enterpriseminer系统的决策树分类算法和logistic回归算法进行岩体的质量分级评价。
In this paper , based on the comprehension of the current research situation , we mainly discussed the problem how to adapt the decision tree in common use to the large scale dataset 针对大数据量、多属性值的情况,对决策树分类器所需属性信息的求解提出了新的改进算法。
