A Design of A Simple Yet Effective Exercise Recommendation System in K-12 Online Learning
This addresses exercise recommendation for K-12 students, but appears incremental as it builds on existing methods with specific improvements.
The paper tackled the problem of recommending exercises for K-12 online learning by proposing a method with three modules, resulting in improved recall and a 0.81% increase in diversity compared to baselines.
We propose a simple but effective method to recommend exercises with high quality and diversity for students. Our method is made up of three key components: (1) candidate generation module; (2) diversity-promoting module; and (3) scope restriction module. The proposed method improves the overall recommendation performance in terms of recall, and increases the diversity of the recommended candidates by 0.81\% compared to the baselines.
