SimStu-Transformer: A Transformer-Based Approach to Simulating Student Behaviour

Li, Zhaoxing and Shi, Lei and Cristea, Alexandra and Zhou, Yunzhan and Xiao, Chenghao and Pan, Ziqi (2022) 'SimStu-Transformer: A Transformer-Based Approach to Simulating Student Behaviour.', in Artificial Intelligence in Education.

Lacking behavioural data between students and an Intelligent Tutoring System (ITS) has been an obstacle for improving its personalisation capability. One feasible solution is to train “sim students”, who simulate real students’ behaviour in the ITS. We can then use their generated behavioural data to train the ITS to offer real students personalised learning strategies and trajectories. In this paper, we thus propose SimStu-Transformer, developed based on the Decision Transformer algorithm, to generate learning behavioural data.
