Safe adaptation in multiagent competition

no code implementations14 Mar 2022 Macheng Shen, Jonathan P. How

Achieving the capability of adapting to ever-changing environments is a critical step towards building fully autonomous robots that operate safely in complicated scenarios.

Scaling Up Multiagent Reinforcement Learning for Robotic Systems: Learn an Adaptive Sparse Communication Graph

no code implementations2 Mar 2020 Chuangchuang Sun, Macheng Shen, Jonathan P. How

Through this sparsity structure, the agents can communicate in an effective as well as efficient way via only selectively attending to agents that matter the most and thus the scale of the MARL problem is reduced with little optimality compromised.

Robust Opponent Modeling via Adversarial Ensemble Reinforcement Learning in Asymmetric Imperfect-Information Games

no code implementations18 Sep 2019 Macheng Shen, Jonathan P. How

In order to achieve a good trade-off between the robustness of the learned policy and the computation complexity, we propose to train a separate opponent policy against the protagonist agent for evaluation purposes.

Active Perception in Adversarial Scenarios using Maximum Entropy Deep Reinforcement Learning

no code implementations14 Feb 2019 Macheng Shen, Jonathan P. How

We pose an active perception problem where an autonomous agent actively interacts with a second agent with potentially adversarial behaviors.

A Probe Towards Understanding GAN and VAE Models

no code implementations13 Dec 2018 Lu Mi, Macheng Shen, Jingzhao Zhang

This project report compares some known GAN and VAE models proposed prior to 2017.

Transferable Pedestrian Motion Prediction Models at Intersections

no code implementations15 Mar 2018 Macheng Shen, Golnaz Habibi, Jonathan P. How

We are interested in developing transfer learning algorithms that can be trained on the pedestrian trajectories collected at one intersection and yet still provide accurate predictions of the trajectories at another, previously unseen intersection.

The Impact of Road Configuration in V2V-based Cooperative Localization: Mathematical Analysis and Real-world Evaluation

no code implementations1 May 2017 Macheng Shen, Jing Sun, Ding Zhao

It has been shown, in our previous work, that the GNSS error can be reduced from several meters to sub-meter level by matching the biased GNSS positioning to a digital map with road constraints.

Optimization of Vehicle Connections in V2V-based Cooperative Localization

no code implementations26 Mar 2017 Macheng Shen, Jing Sun, Ding Zhao

Cooperative map matching (CMM) uses the Global Navigation Satellite System (GNSS) positioning of a group of vehicles to improve the standalone localization accuracy.

Improving Localization Accuracy in Connected Vehicle Networks Using Rao-Blackwellized Particle Filters: Theory, Simulations, and Experiments

no code implementations19 Feb 2017 Macheng Shen, Ding Zhao, Jing Sun, Huei Peng

A Rao-Blackwellized particle filter (RBPF) is used to jointly estimate the common biases of the pseudo-ranges and the vehicle positions.
