Jointly Predicting Courses and Grades Using a Transformer-Based Model
Existing predictive models in learning analytics often treat student academic history as a simple sequence, overlooking the concurrent nature of courses taken within a semester. This simplification can lead to inaccurate performance predictions, particularly for students with heavy or challenging course loads. This paper introduces a TRansformer for Academic Course-grade Estimation (TRACE) that addresses this limitation by jointly predicting both the set of courses a student will take and their corresponding grades for an upcoming semester. Our approach encodes courses on a per-semester basis to capture the effects of course concurrency and utilizes a novel loss function combining course-set prediction with grade prediction. We demonstrate that predicting courses taken in addition to the g
利用基于Transformer的模型同时预测学生下学期选课与成绩,提高预测准确性。
- 核心方法
- 提出了TRansformer for Academic Course-grade Estimation (TRACE)模型,该模型通过按学期编码课程来捕捉课程同时性的影响,并使用了结合课程集预测和成绩预测的新颖损失函数。
- 适合谁读
- 研究者 / 工程师
- 要解决的问题
- 现有学习分析中的预测模型通常将学生学术历史视为简单序列,忽略了课程的同时性,导致对某些学生的表现预测不准确。
- 关键实验
- 通过对比实验展示了TRACE模型在同时预测课程选择和成绩上的优越性,特别是在预测成绩方面比现有模型更准确。
- 主要贡献
- TRACE模型能够同时进行课程选择和成绩预测,提供更准确的学生成绩预测,尤其是对课程负荷重或难度高的学生。
- 意义与局限
- 提高了学习分析的预测准确性,有助于个性化教育支持和资源分配。但由于数据的局限性,模型在不同教育体系下的泛化能力仍需验证。
