| Abstract: | The traditional methods of predicting students’grades often require manual screening of characteristics or a large amount of prior knowledge and expert knowledge, the Graph-AE model based on deep learning is proposed to predict students’performance, which can automatically extract features without manual intervention and does not require a lot of prior knowledge. Comparing the Graph-AE model with 13 classical recommendation algorithms, the experimental results show that the Graph-AE model is more accurate on the students’ performance data set than the traditional solutions and can better characterize the relevance and difference between students and courses. |
