From Parameters to Feature Space: Task Arithmetic for Backdoor Mitigation in Model Merging

ICML 2026poster

Model merging (MM) has gained significant attention as a cost-effective approach to integrate multiple task-specific models into a unified model. However, recent work reveals that MM is highly susceptible to backdoor attacks. Existing defenses based on task arithmetic often fail to eliminate backdoo…

SLRL: Semi-Supervised Local Community Detection Based on Reinforcement Learning

AAAI 2025technical

Most existing semi-supervised community detection algorithms leverage known communities to learn community structures, subsequently identifying communities that align with these learned community structures. However, differences in community structures may render the community structures learned by…
