Genuine Knowledge from Practice: Diffusion Test-Time Adaptation for Video Adverse Weather Removal

no code implementations12 Mar 2024 Yijun Yang, Hongtao Wu, Angelica I. Aviles-Rivero, Yulun Zhang, Jing Qin, Lei Zhu

Although ViWS-Net is proposed to remove adverse weather conditions in videos with a single set of pre-trained weights, it is seriously blinded by seen weather at train-time and degenerates when coming to unseen weather during test-time.

Unleashing Large-Scale Video Generative Pre-training for Visual Robot Manipulation

1 code implementation20 Dec 2023 Hongtao Wu, Ya Jing, Chilam Cheang, Guangzeng Chen, Jiafeng Xu, Xinghang Li, Minghuan Liu, Hang Li, Tao Kong

In this paper, we extend the scope of this effectiveness by showing that visual robot manipulation can significantly benefit from large-scale video generative pre-training.

Vision-Language Foundation Models as Effective Robot Imitators

no code implementations2 Nov 2023 Xinghang Li, Minghuan Liu, Hanbo Zhang, Cunjun Yu, Jie Xu, Hongtao Wu, Chilam Cheang, Ya Jing, Weinan Zhang, Huaping Liu, Hang Li, Tao Kong

We believe RoboFlamingo has the potential to be a cost-effective and easy-to-use solution for robotics manipulation, empowering everyone with the ability to fine-tune their own robotics policy.

Can I Pour into It? Robot Imagining Open Containability Affordance of Previously Unseen Objects via Physical Simulations

1 code implementation5 Aug 2020 Hongtao Wu, Gregory S. Chirikjian

In this letter, we propose a novel method for robots to "imagine" the open containability affordance of a previously unseen object via physical simulations.

"Good Robot!": Efficient Reinforcement Learning for Multi-Step Visual Tasks with Sim to Real Transfer

1 code implementation25 Sep 2019 Andrew Hundt, Benjamin Killeen, Nicholas Greene, Hongtao Wu, Heeyeon Kwon, Chris Paxton, Gregory D. Hager

We are able to create real stacks in 100% of trials with 61% efficiency and real rows in 100% of trials with 59% efficiency by directly loading the simulation-trained model on the real robot with no additional real-world fine-tuning.

Is That a Chair? Imagining Affordances Using Simulations of an Articulated Human Body

1 code implementation17 Sep 2019 Hongtao Wu, Deven Misra, Gregory S. Chirikjian

In our method, the robot "imagines" the affordance of an arbitrarily oriented object as a chair by simulating a physical sitting interaction between an articulated human body and the object.
