Balancing the Experts: Unlocking LoRA-MoE for GRPO via Mechanism-Aware Rewards

ICLR 2026poster

Parameter-efficient Mixture-of-Experts (MoE) architectures, such as LoRA-MoE, enable strong and generalizable fine-tuning. However, a critical problem arises when fine-tuning these architectures with advanced reinforcement learning algorithms such as Group Relative Policy Optimization (GRPO). Tradit…

Stereo Depth Estimation with Echoes

ECCV 2022poster

"Stereo depth estimation is particularly amenable to local textured regions while echoes have good depth estimations for global textureless regions, thus the two modalities complement each other. Motivated by the reciprocal relationship between both modalities, in this paper, we propose an end-to-en…

What And Where To Focus In Person Search

ICASSP 2021accepted

Person search aims to locate and identify the query person from a gallery of original scene images. Almost all previous methods only consider single high-level semantic information, ignoring that the essence of identification task is to learn rich and expressive features. Additionally, large pose va…
