自从人工智能成为一个独立的学科以来,机器学习己经成为该领域的中心研究课题。学习能力是智能的一个必要的组成部分,它己经成为智能计算机系统的一个主要特征。本文就基于机器学习中的决策树算法完成的分类系统进行了说明。
文中着重介绍了作者在设计完成系统过程中的主要工作,根据要系统功能的要求,作者先后完成了文件操作部分,决策树规则的显示和树型结构的图形显示,在完成文件操作时,主要分成数据文件的读入,修改,保存几大模块。规则显示部分作者采用了决策树算法中的ID3算法,详细分析了ID3算法原理,包括信息熵知识,算法原理,以及分析了ID3算法的优劣。利用递规函数完成ID3算法。利用Visual C++ 6.0的CDC类完成了树的图形显示。
本文同时介绍了系统最后能够实现的功能。并通过对不同的实验结果的对比分析直观的显示了系统的具体功能模块的实现。文章的最后做出了总体上的结论,并指出了本分类系统的存在的许多不足之处,这也为以后的进一步研究奠定了基础。

Since artificial intelligence is as a separate disciplines, machine learning has been a center for research topics in the field. Learning ability is a necessary component of wisdom, it has been become one of the main features of smart computer systems. The machine learning on the Jueceshu algorithms based on the completion of the classification system for the statement. The article highlights the author in the design of complete systems of the main course of the work, according to the functional requirements of the system, the author has completed the operational part of the document, Jueceshu rules that the structure and uses graphics show that complete documentation in operation, mainly divided into data files into the time, amend and preserve several large modules. Some rules that the author used Jueceshu algorithms ID3 algorithm, a detailed analysis of ID3 algorithm theory, including information entropy knowledge algorithm theory, and analysis of the merits of ID3 algorithm. Use regulations would function to complete ID3 algorithm. 6.0 using Visual C++ the CDC completed a tree graphs that category. The system also introduced the last to achieve the function. And through different visual comparison and analysis of the results of the experiment showed that the specific functional modules of the system to achieve. The article made the final general conclusions, and noted that the classification system of the presence of many inadequacies, and this also laid a foundation for further study beyond.
