Passive Gravity Compensation for Parallel Mechanism With Both Spatial Translations and Angular Orientations

RA-L 2024

Passive compensation has been proven to be effective in reducing gravitational joint loads and improving the output capability of mechanisms. Existing methods for passive compensation are not satisfactory in terms of mechanism complexity and implementation convenience, while cases with variable angu

Using Human Feedback to Fine-tune Diffusion Models without Any Reward Model

CVPR 2024poster

Using reinforcement learning with human feedback (RLHF) has shown significant promise in fine-tuning diffusion models. Previous methods start by training a reward model that aligns with human preferences then leverage RL techniques to fine-tune the underlying models. However crafting an efficient re…

Neural MMO 2.0: A Massively Multi-task Addition to Massively Multi-agent Learning

NeurIPS 2023poster

Neural MMO 2.0 is a massively multi-agent and multi-task environment for reinforcement learning research. This version features a novel task-system that broadens the range of training settings and poses a new challenge in generalization: evaluation on and against tasks, maps, and opponents never see…
