An Alphabet of Leakage Measures
Atefeh Gilani, Gowtham R. Kurri, Oliver Kosut +1
We introduce a family of information leakage measures called maximal -leakage, parameterized by real numbers and . The measure is formalized via an operational definiti…
Robust Model Selection of Gaussian Graphical Models
Abrar Zahin, Rajasekhar Anguluri, Lalitha Sankar +2
In Gaussian graphical model selection, noise-corrupted samples present significant challenges. It is known that even minimal amounts of noise can obscure the underlying structure,…
PMU Tracker: A Visualization Platform for Epicentric Event Propagation Analysis in the Power Grid
Anjana Arunkumar, Andrea Pinceti, Lalitha Sankar +1
The electrical power grid is a critical infrastructure, with disruptions in transmission having severe repercussions on daily activities, across multiple sectors. To identify, prev…
An Operational Approach to Information Leakage via Generalized Gain Functions
Gowtham R. Kurri, Lalitha Sankar, Oliver Kosut
We introduce a \emph{gain function} viewpoint of information leakage by proposing \emph{maximal -leakage}, a rich class of operationally meaningful leakage measures that subsume…
The Saddle-Point Accountant for Differential Privacy
Wael Alghamdi, Shahab Asoodeh, Flavio P. Calmon +4
We introduce a new differential privacy (DP) accountant called the saddle-point accountant (SPA). SPA approximates privacy guarantees for the composition of DP mechanisms in an acc…
Parameter Estimation in Ill-conditioned Low-inertia Power Systems
Rajasekhar Anguluri, Lalitha Sankar, Oliver Kosut
This paper examines model parameter estimation in dynamic power systems whose governing electro-mechanical equations are ill-conditioned or singular. This ill-conditioning is becau…
