Abstract

C4.5 algorithm is one of the ten classic algorithms of data mining, it is a series of algorithms used in machine learning and data mining. This paper mainly studies the application of C4.5 algorithm to the analysis of performance data, to dig out the hidden relationship between various factors and test results, to provide a fair and objective analysis of the quality of the teaching assessment and provide decision support for the teaching improvement in the future. This paper focuses on the C4.5 algorithm, including the division rules, the calculation of the information gain rate and algorithm workflow, and finally through an example to explain the specific application of the C4.5 algorithm.
