Application And Research Of Data Mining Algorithm In Special Police Training And Evaluation System

With the development of the world peacekeeping situation,special police as a national group of special groups,bear the anti-terrorism stability,is to maintain the national security and stability of the situation of a vital force.So for the special police's physical fitness and professional skills have a very high demand,which is inseparable from the usual special police training in all aspects.Not only have a good cultural and other theoretical basis,but also have a strong physical fitness to deal with all kinds of emergency emergencies.In the era of rapid development of the Internet and information explosion,the traditional training data is nothing more than the results of various training subjects,instructors and leaders can only rank from the various subjects such as the analysis of the special police situation.This form is too simple,and it is difficult from a large number of subjects to find out the factors that restrict the development of each other.Data mining technology can be from a large number of databases to find the results of the intrinsic link for the special police instructors and leaders to provide better decisionmaking.By analyzing the association rules mining and classification mining in data mining technology,the traditional algorithm of apriori and fp-growth is analyzed,and the principle and application of the algorithm are pointed out.Combined with the information of police officers,Improved algorithm based on treemap.Then,the traditional decision tree id3,c4.5 and random forest algorithm are analyzed,and an improved algorithm of global discretization is proposed.By comparing the 12 test datasets in UCI,the c4.5 and rf algorithms are compared,The difference between the running speed and the accuracy of each data set after discretization and discretization shows that there is a significant improvement in the accuracy of the data set after the global discretization.Finally,the design and implementation of special police quality evaluation system,the two data mining algorithms applied to the system.In the existing special police basic information and training subjects score data in a large number of rules,the special police after their own direction of the future direction,for the special police instructors and leaders also played a decision-making and support role.
