The Research And Application Of Cluster Analysis On The Public Security Specialist Examination Analyze System

With the development of computer technology, more and more online examination system is applying to the modern education. The subject comes from the Public Security synthetical information training platform,Exam analysis system,which using a variety of metrics to analyze student test score and cluster technology to divide students. The study object of this article is designing a scientific, impartial, high quality analysis.This paper first briefed on research status of traditional examination analyze,and analyzes on the problems faced by the traditional examination analyze. Then, in the exam analysis system, Propose the use of clustering technology to divide the students. Next, the paper describes the commonly used clustering algorithm,the characteristics of various algorithms and determines using the K-means clustering algorithm as the clustering algorithm,studies on the process and the characteristics of the algorithm.Then, this paper puts forward the optimization for the problem of selecting the parameters in the application of the algorithm, and verifies the effectiveness of the optimization K-means through the experiment, Finally, based on customer demand for the System, design the overall framework,function modules of the system, and implement system of examination analyze, and the system runs well.Finally, the paper make a summary, and puts forward the tentative idea to improve the examination analysis by clustering technology.
