Talk Title: Reliable Low Latency Communications for Connected Autonomy: Experienced Deep Learning and Control
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: In this talk, we provide an overview on the frontier of research in the area of ultra reliable low latency communications (URLLC) for connected autonomy. In particular, we first introduce a novel framework, dubbed experienced deep learning, that combines deep reinforcement learning with generative adversarial networks (GANs) to enable model-free URLLC under limited data availability and without requiring any knowledge or assumptions on the delay models of the wireless users. This framework is particularly suitable to enable reliable and low latency connectivity for connected autonomy applications whose performance is highly sensitive to the dynamics of the wireless network environment. We show how the proposed framework can intelligently optimize wireless resources while balancing the tradeoff between reliability, latency, and rate. This approach presents a major departure from prior URLLC approaches that often ignore the rate requirements of the users and rely on historic data or on unrealistic delay modeling assumptions. Then, we turn our attention to the problem of joint communications and control for autonomous connected vehicles. In this area, we introduce a new cyber-physical approach for characterizing the wireless reliability of an autonomous vehicle system while being explicitly cognizant of its control system requirements. After characterizing reliability, we show how one can optimize the operation of the autonomous vehicle system while jointly taking into account the delay of the vehicular network and the stability of the control system The synergies between URLLC and control system designs are then discussed. We conclude the talk with an overview on future opportunities in these exciting areas.
