Summary: | Engagement between instructors and students plays a crucial role in enhancing
students'academic performance. However, instructors often struggle to provide
timely and personalized support in large classes. To address this challenge, we
propose a novel Virtual Teaching Assistant (VTA) named YA-TA, designed to offer
responses to students that are grounded in lectures and are easy to understand.
To facilitate YA-TA, we introduce the Dual Retrieval-augmented Knowledge Fusion
(DRAKE) framework, which incorporates dual retrieval of instructor and student
knowledge and knowledge fusion for tailored response generation. Experiments
conducted in real-world classroom settings demonstrate that the DRAKE framework
excels in aligning responses with knowledge retrieved from both instructor and
student sides. Furthermore, we offer additional extensions of YA-TA, such as a
Q&A board and self-practice tools to enhance the overall learning experience.
