We consider the quantum \emph{symmetric} private information retrieval (QSPIR) problem in a system with databases and messages, with unresponsive servers, -colluding…
Private Counterfactual Retrieval With Immutable Features
Shreya Meel, Pasan Dissanayake, Mohamed Nomeir +2
In a classification task, counterfactual explanations provide the minimum change needed for an input to be classified into a favorable class. We consider the problem of privately r…
Joint Age-State Belief is All You Need: Minimizing AoII via Pull-Based Remote Estimation
Ismail Cosandal, Sennur Ulukus, Nail Akar
Age of incorrect information (AoII) is a recently proposed freshness and mismatch metric that penalizes an incorrect estimation along with its duration. Therefore, keeping track of…
Age of Gossip With Time-Varying Topologies
Arunabh Srivastava, Thomas Jacob Maranzatto, Sennur Ulukus
We consider a gossiping network, where a source node sends updates to a network of gossiping nodes. Meanwhile, the connectivity topology of the gossiping network changes over t…
Scheduling Policies in a Multi-Source Status Update System with Dedicated and Shared Servers
Sahan Liyanaarachchi, Sennur Ulukus, Nail Akar
Use of multi-path network topologies has become a prominent technique to assert timeliness in terms of age of information (AoI) and to improve resilience to link disruptions in com…
Private Counterfactual Retrieval
Mohamed Nomeir, Pasan Dissanayake, Shreya Meel +2
Transparency and explainability are two extremely important aspects to be considered when employing black-box machine learning models in high-stake applications. Providing counterf…
Age of Gossip with the Push-Pull Protocol
Arunabh Srivastava, Thomas Jacob Maranzatto, Sennur Ulukus
We consider a wireless network where a source generates packets and forwards them to a network containing nodes. The nodes in the network use the asynchronous push, pull or pus…
Mobility in Age-Based Gossip Networks
Arunabh Srivastava, Sennur Ulukus
We consider a gossiping network where a source forwards updates to a set of gossiping nodes that are placed in an arbitrary graph structure and gossip with their neighbors. In…
Age of Gossip in Networks with Multiple Views of a Source
Kian J. Khojastepour, Matin Mortaheb, Sennur Ulukus
We consider the version age of information (AoI) in a network where a subset of nodes act as sensing nodes, sampling a source that in general can follow a continuous distribution.…
Modeling Interfering Sources in Shared Queues for Timely Computations in Edge Computing Systems
Nail Akar, Melih Bastopcu, Sennur Ulukus +1
Most existing stochastic models on age of information (AoI) focus on a single shared server serving status update packets from sources where each packet update stream is Pois…
6G at : The Future of Cislunar Communications
Sahan Liyanaarachchi, Stavros Mitrolaris, Purbesh Mitra +1

Multi-Threshold AoII-Optimum Sampling Policies for CTMC Information Sources
Ismail Cosandal, Nail Akar, Sennur Ulukus
We study push-based sampling and transmission policies for a status update system consisting of a general finite-state continuous-time Markov chain (CTMC) information source with k…
Cyclic Scheduler Design for Minimizing Age of Information in Massive Scale Networks Susceptible to Packet Errors
Sahan Liyanaarachchi, Sennur Ulukus, Nail Akar
In multi-source status update systems, sources need to be scheduled appropriately to maintain timely communication between each of the sources and the monitor. A cyclic schedule is…
