Theoretical Performance Guarantees for Partial Domain Adaptation via Partial Optimal Transport
Jayadev Naram, Fredrik Hellström, Ziming Wang +2
In many scenarios of practical interest, labeled data from a target distribution are scarce while labeled data from a related source distribution are abundant. One particular setti…
Type-Based Unsourced Multiple Access over Fading Channels with Cell-Free Massive MIMO
Kaan Okumus, Khac-Hoang Ngo, Giuseppe Durisi +1
Type-based unsourced multiple access (TUMA) is a recently proposed framework for type-based estimation in massive uncoordinated access networks. We extend the existing design of TU…
An Achievability Bound for Type-Based Unsourced Multiple Access
Deekshith Pathayappilly Krishnan, Kaan Okumus, Khac-Hoang Ngo +1
We derive an achievability bound to quantify the performance of a type-based unsourced multiple access system -- an information-theoretic model for grant-free multiple access with…
Information Age and Correctness for Energy Harvesting Devices with Random Access
Khac-Hoang Ngo, Giuseppe Durisi, Petar Popovski
We investigate accuracy and freshness of status updates from a large number of energy-harvesting devices that monitor two-state Markov processes and access the medium using the slo…
