The Mirage of Model Editing: Revisiting Evaluation in the Wild

Wanli Yang, Fei Sun, Jiajun Tan +5

Despite near-perfect results reported in the literature, the effectiveness of model editing in real-world applications remains unclear. To bridge this gap, we introduce QAEdit, a n…

Fact-Level Confidence Calibration and Self-Correction

Yige Yuan, Bingbing Xu, Hexiang Tan +5

Confidence calibration in LLMs, i.e., aligning their self-assessed confidence with the actual accuracy of their responses, enabling them to self-evaluate the correctness of their o…
