Near-Field Channel Estimation in Dual-Band XL-MIMO with Side Information-Assisted Compressed Sensing

no code implementations • 19 Mar 2024 • Haochen Wu, Liyang Lu, Zhaocheng Wang

Specifically, we formulate the dual-band near-field communication model based on the fact that high-frequency systems are likely to be deployed with lower-frequency systems.

SafeAR: Safe Algorithmic Recourse by Risk-Aware Policies

no code implementations • 23 Aug 2023 • Haochen Wu, Shubham Sharma, Sunandita Patra, Sriram Gopalakrishnan

However, the uncertainties of feature changes and the risk of higher than average costs in recourse have not been considered.

Multiagent Inverse Reinforcement Learning via Theory of Mind Reasoning

1 code implementation • 20 Feb 2023 • Haochen Wu, Pedro Sequeira, David V. Pynadath

We evaluate our approach in a simulated 2-player search-and-rescue operation where the goal of the agents, playing different roles, is to search for and evacuate victims in the environment.

Task Allocation with Load Management in Multi-Agent Teams

no code implementations • 17 Jul 2022 • Haochen Wu, Amin Ghadami, Alparslan Emrah Bayrak, Jonathon M. Smereka, Bogdan I. Epureanu

In this work, we present a decision-making framework for multi-agent teams to learn task allocation with the consideration of load management through decentralized reinforcement learning, where idling is encouraged and unnecessary resource usage is avoided.
