Graph-based Approaches and Functionalities in Retrieval-Augmented Generation: A Comprehensive Survey

Zulun Zhu, Tiancheng Huang, Kai Wang +3

Large language models (LLMs) struggle with the factual error during inference due to the lack of sufficient training data and the most updated knowledge, leading to the hallucinati…

MalruleLib: Large-Scale Executable Misconception Reasoning with Step Traces for Modeling Student Thinking in Mathematics

Xinghe Chen, Naiming Liu, Shashank Sonkar

Student mistakes in mathematics are often systematic: a learner applies a coherent but wrong procedure and repeats it across contexts. We introduce MalruleLib, a learning-science-g…

The Imitation Game for Educational AI

Shashank Sonkar, Naiming Liu, Xinghe Chen +1

As artificial intelligence systems become increasingly prevalent in education, a fundamental challenge emerges: how can we verify if an AI truly understands how students think and…
