| Abstract: | Data mining has obtained extensive research and the application since its appearance. The C4.5 algorithm is already more mature in classifying technique of data,but the application of data mining of students' achievement is rather few. The article initially studies the main classification technology,and introduces in detail decision tree C4.5 algorithm. The article takes data of the actual students' achievement as a basis to mine data for students' achievement. By the analysis of the result of data mining,w... |
