Dismantling the Illusion of Vision-Language-Action Models Competence via Explicit Distributional Shifts

ICML 2026poster

Given that simulation can never exhaustively enumerate reality, generalization is the determining factor for whether Vision-Language-Action (VLA) models can translate benchmark success into real-world functionality. However, current evaluation protocols often incentivize mechanical memorization rath…

Merge Hijacking: Backdoor Attacks to Model Merging of Large Language Models

ACL 2025long

Model merging for Large Language Models (LLMs) directly fuses the parameters of different models finetuned on various tasks, creating a unified model for multi-domain tasks. However, due to potential vulnerabilities in models available on open-source platforms, model merging is susceptible to backdo…
