数据分析公共服务平台上K-Means算法的集成实现

摘要

The platform to provide the service of data analysis need to integrate a variety of data analysis algorithm,K-Means algorithm was provided as an example,the main work of the integration of K-Means-Agorithm was given.The main work include how to extract parameters,and how to integrate the user's data files.To realizate this two point,the plateform designs the contorl for user to configurate the parameters and designs the interface for calling interface of K-Means algorithm.The parameters of K-Means was analyzed and extracted,then selected the appropriate controls to display in the JSP page.The background program calls the algorithm based on user configuration interface,realize the analysis of the data.Then call the interface of JFreeChart to display the result as a pie chart and show users.%为用户提供数据分析的公共服务平台上需要集成多种数据分析算法,以平台集成K-Means算法为例,给出该算法与平台集成时所做的主要工作,包括如何提取算法的一些参数,以及用户数据如何与平台的算法集成,为实现2者的集成,平台设计了用户配置参数的控件,以及对K-Means算法调用的接口.对K-Means算法的参数进行分析,并提取用户可配置的参数,选取合适的控件显示在JSP页面上,后台程序根据用户的配置调用算法接口,实现对数据的分析.平台算法实现对用户数据的分析并调用JFreeChart接口以饼状图的形式把分析结果显示在界面上呈现给用户.
