Enabling Large Intelligent Surfaces With Compressive Sensing and Deep Learning

Abdelrahman Taha, Muhammad Alrabeiah, Ahmed Alkhateeb

This paper presents a novel architecture for large intelligent surfaces by leveraging compressive sensing and deep learning tools. The architecture keeps the majority of its reflection matrix elements passive while nearly eliminating the training overhead required for the passive elements.

Collision Avoidance in Pedestrian-Rich Environments With Deep Reinforcement Learning

Michael Everett, Yu Fan Chen, Jonathan P. How

In an effort to make the navigation of robots collision-free, a deep reinforcement model is effectively employed, which handles a potentially large and time-varying number of nearby, decision-making agents with a single learned policy.
