DOPE: Doubly Optimistic and Pessimistic Exploration for Safe Reinforcement Learning
Archana Bura, Aria HasanzadeZonuzy, Dileep Kalathil +2
Safe reinforcement learning is extremely challenging--not only must the agent explore an unknown environment, it must do so while ensuring no safety constraint violations. We formu…
Non-adiabatic dynamics of the entanglement entropy in a symmetry-breaking Haldane insulator
Junjun Xu
We study the non-adiabatic dynamics of a typical symmetry-protected topological phase-the Haldane insulator phase with broken bond-centered inversion. By continuously breaking the…
LDPC Codes with Soft Interference Cancellation for Uncoordinated Unsourced Multiple Access
Asit Kumar Pradhan, Vamsi K. Amalladinne, Krishna R. Narayanan +1
This article presents a novel enhancement to the random spreading based coding scheme developed by Pradhan et al.\ for the unsourced multiple access channel. The original coding sc…
Approximate Support Recovery using Codes for Unsourced Multiple Access
Michail Gkagkos, Asit Kumar Pradhan, Vamsi Amalladinne +3
We consider the approximate support recovery (ASR) task of inferring the support of a -sparse vector from noisy measurements. We examine the case…
Coded Compressed Sensing with Successive Cancellation List Decoding for Unsourced Random Access with Massive MIMO
Vamsi K. Amalladinne, Jean-Francois Chamberland, Krishna R. Narayanan
Unsourced random access (URA) is an increasingly popular communication paradigm attuned to machine driven data transfers in \textit{Internet-of-Things} (IoT) networks. In a typical…
Stochastic Binning and Coded Demixing for Unsourced Random Access
Jamison R. Ebert, Vamsi K. Amalladinne, Stefano Rini +2
Unsourced random access is a novel communication paradigm designed for handling a large number of uncoordinated users that sporadically transmit very short messages. Under this mod…
Multi-Class Unsourced Random Access via Coded Demixing
Vamsi K. Amalladinne, Allen Hao, Stefano Rini +1
Unsourced random access (URA) is a recently proposed communication paradigm attuned to machine-driven data transfers. In the original URA formulation, all the active devices share…
