Proximal Policy Optimization Learning based Control of Congested Freeway Traffic

no code implementations12 Apr 2022 Shurong Mo, Nailong Wu, Jie Qi, Anqi Pan, Zhiguang Feng, Huaicheng Yan, Yueying Wang

The control gains for the three feedbacks are learned from the interaction between the PPO and the numerical simulator of the traffic system without knowing the system dynamics.

Morphological feature visualization of Alzheimer's disease via Multidirectional Perception GAN

no code implementations25 Nov 2021 Wen Yu, Baiying Lei, Yanyan Shen, Shuqiang Wang, Yong liu, Zhiguang Feng, Yong Hu, Michael K. Ng

In this work, a novel Multidirectional Perception Generative Adversarial Network (MP-GAN) is proposed to visualize the morphological features indicating the severity of AD for patients of different stages.
