DIACDM: COGNITIVE DIAGNOSIS IN TEACHER-STUDENT DIALOGUES USING THE INITIATION-RESPONSE-EVALUATION FRAMEWORK

ICASSP 2026poster

While cognitive diagnosis (CD) effectively assesses students' knowledge mastery from structured test data, applying it to real-world teacher-student dialogues presents two fundamental challenges. Traditional CD models lack a suitable framework for handling dynamic, unstructured dialogues, and it's d…

Hallucination Begins Where Saliency Drops

ICLR 2026oral

Recent studies have investigated attention dynamics in large vision language models (LVLMs), yet existing methods remain limited in reliably distinguishing hallucinated from correct outputs — primarily because they rely solely on forward-pass attention, ignoring gradient-based signals that reveal ho…

S^2-KD: Semantic-Spectral Knowledge Distillation Spatiotemporal Forecasting

AAAI 2026technical

Spatiotemporal forecasting often relies on computationally intensive models to capture complex dynamics. Knowledge distillation (KD) has emerged as a key technique for creating lightweight student models, with recent advances like frequency-aware KD successfully preserving spectral properties (i.e.,
