FPEdit: Robust LLM Fingerprinting through Localized Parameter Editing

Published in arXiv preprint, 2025

We introduce FPEdit, a novel framework that leverages knowledge editing to inject semantically coherent natural language fingerprints through sparse, targeted modifications to model weights, achieving 95-100% fingerprint retention under both full-parameter fine-tuning and parameter-efficient adaptation.

DiG: Differential Grounding for Enhancing Fine-Grained Perception in Multimodal Large Language Model

Published in CVPR 2026, 2025

We introduce DiG (Differential Grounding), a novel proxy task framework where MLLMs learn fine-grained perception by identifying and localizing all differences between similar image pairs, significantly improving performance across diverse visual perception benchmarks.
