Transition-Aware Multi-Activity Knowledge Tracing
Siqian Zhao, Chunpai Wang, Shaghayegh Sahebi
Accurate modeling of student knowledge is essential for large-scale online learning systems that are increasingly used for student training. Knowledge tracing aims to model student…
Knowledge Tracing for Complex Problem Solving: Granular Rank-Based Tensor Factorization
Chunpai Wang, Shaghayegh Sahebi, Siqian Zhao +2
Knowledge Tracing (KT), which aims to model student knowledge level and predict their performance, is one of the most important applications of user modeling. Modern KT approaches…
Block-Structured Optimization for Subgraph Detection in Interdependent Networks
Fei Jie, Chunpai Wang, Feng Chen +2
We propose a generalized framework for block-structured nonconvex optimization, which can be applied to structured subgraph detection in interdependent networks, such as multi-laye…
Calibrated Nonparametric Scan Statistics for Anomalous Pattern Detection in Graphs
Chunpai Wang, Daniel B. Neill, Feng Chen
We propose a new approach, the calibrated nonparametric scan statistic (CNSS), for more accurate detection of anomalous patterns in large-scale, real-world graphs. Scan statistics…
Modeling Knowledge Acquisition from Multiple Learning Resource Types
Siqian Zhao, Chunpai Wang, Shaghayegh Sahebi
Students acquire knowledge as they interact with a variety of learning materials, such as video lectures, problems, and discussions. Modeling student knowledge at each point during…
