From Static Constraints to Dynamic Adaptation: Sample-Level Constraint Release for Offline-to-Online Reinforcement Learning

ICML 2026poster

Offline-to-online reinforcement learning (O2O RL) faces a central challenge between retaining offline conservatism and adapting to online feedback under distribution shift. This challenge arises because data behavior evolves during fine-tuning, rendering data origin a misleading basis for constraint…

FED-PsyAU: Privacy-Preserving Micro-Expression Recognition via Psychological AU Coordination and Dynamic Facial Motion Modeling

ICCV 2025poster

Micro-expressions (MEs) are brief, low-intensity, often localized facial expressions. They could reveal genuine emotions individuals may attempt to conceal, valuable in contexts like criminal interrogation and psychological counseling. However, ME recognition (MER) faces challenges, such as small sa…

Boosting Pruned Networks with Linear Over-Parameterization

ICASSP 2024accepted

Structured pruning is a popular technique for reducing the computational cost and memory footprint of neural networks by removing channels. It often leads to a decrease in network accuracy, which can be restored through fine-tuning. However, as the pruning ratio increases, it becomes progressively m…
