Disentangling Knowledge States with Ability and Proficiency Modeling for Knowledge Tracing
Duantengchuan Li, Yingqian Bi, Jinsong Chen +2
The paper introduces Phase-Aware Knowledge Tracing (PAKT), a method that separates student interaction data into ability-building and proficiency phases to better predict future pe…
MBP-KT: Learning Global Collaborative Information from Meta-Behavioral Pattern for Enhanced Knowledge Tracing
Yuhao Jia, Duantengchuan Li, Jinsong Chen +4
The emerging collaborative information-based knowledge tracing (KT) has been a promising way to enhance modeling of learners' knowledge states. The core idea is to extract the coll…
Confident RAG: Enhancing the Performance of LLMs for Mathematics Question Answering through Multi-Embedding and Confidence Scoring
Shiting Chen, Zijian Zhao, Jinsong Chen
Large Language Models (LLMs) hold significant promise for mathematics education, yet they often struggle with complex mathematical reasoning. While Retrieval-Augmented Generation (…
Mixture of Message Passing Experts with Routing Entropy Regularization for Node Classification
Xuanze Chen, Jiajun Zhou, Yadong Li +3
Graph neural networks (GNNs) have achieved significant progress in graph-based learning tasks, yet their performance often deteriorates when facing heterophilous structures where c…
Documents Are People and Words Are Items: A Psychometric Approach to Textual Data with Contextual Embeddings
