Controlling Federated Learning for Covertness
Adit Jain, Vikram Krishnamurthy
A learner aims to minimize a function by repeatedly querying a distributed oracle that provides noisy gradient evaluations. At the same time, the learner seeks to hide $\arg\mi…
Multiple-stopping time Sequential Detection for Energy Efficient Mining in Blockchain-Enabled IoT
Anurag Gupta, Vikram Krishnamurthy
What are the optimal times for an Internet of Things (IoT) device to act as a blockchain miner? The aim is to minimize the energy consumed by low-power IoT devices that log their d…
Dynamics of Social Networks: Multi-agent Information Fusion, Anticipatory Decision Making and Polling
Vikram Krishnamurthy
This paper surveys mathematical models, structural results and algorithms in controlled sensing with social learning in social networks. Part 1, namely Bayesian Social Learning wit…
How can a Radar Mask its Cognition?
Kunal Pattanayak, Vikram Krishnamurthy, Christopher Berry
A cognitive radar is a constrained utility maximizer that adapts its sensing mode in response to a changing environment. If an adversary can estimate the utility function of a cogn…
Adaptive Filtering Algorithms for Set-Valued Observations -- Symmetric Measurement Approach to Unlabeled and Anonymized Data
Vikram Krishnamurthy
Suppose simultaneous independent stochastic systems generate observations, where the observations from each system depend on the underlying parameter of that system. The observ…
Quickest Detection for Human-Sensor Systems using Quantum Decision Theory
Luke Snow, Vikram Krishnamurthy, Brian M. Sadler
In mathematical psychology, recent models for human decision-making use Quantum Decision Theory to capture important human-centric features such as order effects and violation of t…
