A Dynamics Perspective of Pursuit-Evasion Games of Intelligent Agents with the Ability to Learn

no code implementations3 Apr 2021 Hao Xiong, Huanhui Cao, Lin Zhang, Wenjie Lu

It is shown that, in a pursuit-evasion game with a dynamics formulation, an evader is not able to escape from a slightly faster pursuer with an effective learned pursuit strategy, based on agile maneuvers and an effective learned evasion strategy.

Multiple Sclerosis Lesion Inpainting Using Non-Local Partial Convolutions

no code implementations24 Dec 2018 Hao Xiong, Chaoyue Wang, DaCheng Tao, Michael Barnett, Chenyu Wang

However, existing methods inpaint lesions based on texture information derived from local surrounding tissue, often leading to inconsistent inpainting and the generation of artifacts such as intensity discrepancy and blurriness.
