Prescribing Deep Attentive Score Prediction Attracts Improved Student Engagement

no code implementations27 Apr 2020 Youngnam Lee, Byung-soo Kim, Dongmin Shin, JungHoon Kim, Jineon Baek, Jinhwan Lee, Youngduck Choi

To that end, we apply a state-of-the-art deep attentive neural network-based score prediction model to Santa, a multi-platform English ITS with approximately 780K users in South Korea that exclusively focuses on the TOEIC (Test of English for International Communications) standardized examinations.

no code implementations14 Feb 2020 Youngnam Lee, Dongmin Shin, HyunBin Loh, Jaemin Lee, Piljae Chae, Junghyun Cho, Seoyon Park, Jinhwan Lee, Jineon Baek, Byung-soo Kim, Youngduck Choi

First, we define the concept of the study session, study session dropout and study session dropout prediction task in a mobile learning environment.

Towards an Appropriate Query, Key, and Value Computation for Knowledge Tracing

5 code implementations14 Feb 2020 Youngduck Choi, Youngnam Lee, Junghyun Cho, Jineon Baek, Byung-soo Kim, Yeongmin Cha, Dongmin Shin, Chan Bae, Jaewe Heo

To the best of our knowledge, this is the first work to suggest an encoder-decoder model for knowledge tracing that applies deep self-attentive layers to exercises and responses separately.

no code implementations1 Jan 2020 Youngduck Choi, Youngnam Lee, Junghyun Cho, Jineon Baek, Dongmin Shin, Hangyeol Yu, Yugeun Shim, Seewoo Lee, JongHun Shin, Chan Bae, Byungsoo Kim, Jaewe Heo

However, such methods fail to utilize the full range of student interaction data available and do not model student learning behavior.

EdNet: A Large-Scale Hierarchical Dataset in Education

1 code implementation6 Dec 2019 Youngduck Choi, Youngnam Lee, Dongmin Shin, Junghyun Cho, Seoyon Park, Seewoo Lee, Jineon Baek, Chan Bae, Byung-soo Kim, Jaewe Heo

With advances in Artificial Intelligence in Education (AIEd) and the ever-growing scale of Interactive Educational Systems (IESs), data-driven approach has become a common recipe for various tasks such as knowledge tracing and learning path recommendation.
