A sufficient condition for the quasipotential to be the rate function of the invariant measure of countable-state mean-field interacting particle systems
Sarath Yasodharan, Rajesh Sundaresan
This paper considers the family of invariant measures of Markovian mean-field interacting particle systems on a countably infinite state space and studies its large deviation asymp…
The Four Levels of Fixed-Points in Mean-Field Models
Sarath Yasodharan, Rajesh Sundaresan
The fixed-point analysis refers to the study of fixed-points that arise in the context of complex systems with many interacting entities. In this expository paper, we describe four…
Learning to Detect an Odd Restless Markov Arm with a Trembling Hand
P. N. Karthik, Rajesh Sundaresan
This paper studies the problem of finding an anomalous arm in a multi-armed bandit when (a) each arm is a finite-state Markov process, and (b) the arms are restless. Here, anomaly…
Cohorting to isolate asymptomatic spreaders: An agent-based simulation study on the Mumbai Suburban Railway
Alok Talekar, Sharad Shriram, Nidhin Vaidhiyan +10
The Mumbai Suburban Railways, \emph{locals}, are a key transit infrastructure of the city and is crucial for resuming normal economic activity. To reduce disease transmission, poli…
COVID-19: Optimal Design of Serosurveys for Disease Burden Estimation
Siva Athreya, Giridhara R. Babu, Aniruddha Iyer +6
We provide a methodology by which an epidemiologist may arrive at an optimal design for a survey whose goal is to estimate the disease burden in a population. For serosurveys with…
A Distributed Hierarchy Framework for Enhancing Cyber Security of Control Center Applications
Chetan Kumar Kuraganti, Bryan Paul Robert, Gurunath Gurrala +4
Recent cyber-attacks on power grids highlight the necessity to protect the critical functionalities of a control center vital for the safe operation of a grid. Even in a distribute…
