Learning a Structured Neural Network Policy for a Hopping Task

, 2018
In this work we present a method for learning a reactive policy for a simple dynamic locomotion task involving hard impact and switching contacts where we assume the contact location and contact timing to be unknown.

Cyrus+: A DRL-Based Puncturing Solution to URLLC/eMBB Multiplexing in O-RAN

IEEE Transactions on Machine Learning in Communications and Networking
Puncturing is a promising technique in 3GPP to multiplex Enhanced Mobile Broadband (eMBB) and Ultra-Reliable Low Latency Communications (URLLC) traffic on the same 5G New Radio (NR) air interface. The essence of puncturing is to transmit URLLC packets on

Exploring Y1 Communications and Services in O-RAN: Background, Privacy, and Security

IEEE Open Journal of the Communications Society
In the latest open radio access network (O-RAN) architecture, the Y1 interface has been introduced to grant authorized parties, known as Y1 consumers, access to and utilization of Y1 data within the near-real-time RAN intelligent controller (Near-RT RIC).

Mobilized ad-hoc networks: A reinforcement learning approach [PDF]

, 2003
Research in mobile ad-hoc networks has focused on situations in which nodes have no control over their movements. We investigate an important but overlooked domain in which nodes do have control over their movements. Reinforcement learning methods can be

Is There Light at the Ends of the Tunnel? Wireless Sensor Networks for Adaptive Lighting in Road Tunnels [PDF]

, 2011
Existing deployments of wireless sensor networks (WSNs) are often conceived as stand-alone monitoring tools. In this paper, we report instead on a deployment where the WSN is a key component of a closed-loop control system for adaptive lighting in ...

Learning Control Lyapunov Functions from Counterexamples and Demonstrations

, 2019
We present a technique for learning control Lyapunov-like functions, which are used in turn to synthesize controllers for nonlinear dynamical systems that can stabilize the system, or satisfy specifications such as remaining inside a safe set, or ...
