决策树算法在医院数据挖掘中的应用探索

摘要

介绍决策树的基本原理,对决策树算法在医院信息系统中的应用进行研究,以肝癌为例对医院临床数据进行挖掘,经过数据预处理,应用ID3算法建立完整的决策树.用测试数据测试,该决策树具有很高的准确率,指出决策树算法在医院信息系统中具有广泛的应用前景.%The paper introduces the basic principles of decision tree and studies the application of decision tree in hospital information system. Taking liver cancer as an example for clinical data mining, data preprocessing, after application of ID3 algorithm, establishing a complete decision tree, using test data to test the decision tree which has a higher degree of accuracy, the paper Imitates out that decision tree algorithm in the hospital information system has wide range of applications.
