From Exploration to Exploitation: A Two-Stage Entropy RLVR Approach for Noise-Tolerant MLLM Training

CVPR 2026

Reinforcement Learning with Verifiable Rewards (RLVR) for Multimodal Large Language Models (MLLMs) is highly dependent on high-quality labeled data, which is often scarce and prone to substantial annotation noise in real-world scenarios. Existing unsupervised RLVR methods, including pure entropy min

Spike-IMU: An Accurate and Low-Power Spiking Neural Network for Pedestrian Velocity Estimation

ICRA 2026poster

Accurate pedestrian navigation on edge devices is a critical problem. While artificial neural networks (ANNs) have been shown to effectively solve this problem with acceptable accuracy, their energy consumption limits applications on low-power computation platforms. Spiking neural networks (SNNs) ar…

MPGNet: Learning Move-Push-Grasping Synergy for Target-Oriented Grasping in Occluded Scenes

IROS 2024poster

This paper focuses on target-oriented grasping in occluded scenes, where the target object is specified by a binary mask and the goal is to grasp the target object with as few robotic manipulations as possible. Most existing methods rely on a push-grasping synergy to complete this task. To deliver a…

Direct Trajectory Optimization of Free-Floating Space Manipulator for Reducing Spacecraft Variation

RA-L 2022

This letter investigates the direct trajectory optimization of the free-floating space manipulator (FFSM). The main purpose is to plan the joint space trajectories to reduce the spacecraft motion due to the joint rotation during the FFSM performing tasks. To improve the calculation efficiency, the a
