Application Of Data Mining In The Overall Quality Of The College Students

With the expansion of the scale of college students,college students continue to change the way,how to measure the comprehensive quality of college students to become an important concern of school administrators.The comprehensive quality of college students is not only related to the interests of students themselves,but also the social evaluation of the school also played an important role.At present,the software of student status management is diverse,and it can be well adapted to the daily work of teaching management.However,most of these software are biased towards the basic statistics of this category.The comprehensive analysis and evaluation of data are relatively less.The development of a set of effective comprehensive quality analysis system for college students has an important role in improving school management and improving work efficiency.In this paper,through the study of college students in the school during the school,participate in activities,published scientific research and other data information mining,the use of reasonable means of mining,access to comprehensive quality of students in the relationship between the various types of indicators.The main work of this paper is as follows:1.The use of analytic hierarchy process of the comprehensive quality of the indicators of the weights of the calculation,according to the size of the weight of the size of the judge whether the index is the key attribute of the system mining,Many,the decision tree is too large,the formation of the mining rules do not achieve a good evaluation results.And reduce the mining of data can also reduce the workload of pre-processing data,improve the efficiency of mining.2.The use of decision tree C4.5 algorithm,the establishment of comprehensive quality of college students decision tree classification model,through the model to generate the classification rules.Analysis of classification rules,to discover the key factors that affect the overall quality of the ability to achieve the school management personnel to provide scientific data based on the purpose.3.Design and realize the comprehensive quality analysis system of college students,and apply the decision tree classification algorithm to the function module of the system.The realization and operation of the system is beneficial to the students' learning work and to promote the school to carry out the comprehensive quality evaluation work efficiently,which is of great significance to cultivate the high quality students in colleges and universities.
