Fair Differentially Private Federated Learning Framework
Ayush K. Varshney, Sonakshi Garg, Arka Ghosh +1
Federated learning (FL) is a distributed machine learning strategy that enables participants to collaborate and train a shared model without sharing their individual datasets. Priv…
Orbit-finite linear programming
Arka Ghosh, Piotr Hofman, Sławomir Lasota
An infinite set is orbit-finite if, up to permutations of the underlying structure of atoms, it has only finitely many elements. We study a generalisation of linear programming whe…
The Geometry of Reachability in Continuous Vector Addition Systems with States
Shaull Almagor, Arka Ghosh, Tim Leys +1
We study the geometry of reachability sets of continuous vector addition systems with states (VASS). In particular we establish that they are almost Minkowski sums of convex cones…
Quasi-spiral solution to the mixed intracluster medium and the universal entropy profile of galaxy clusters
Uri Keshet, Itay Raveh, Arka Ghosh
Well-resolved galaxy clusters often show a large-scale quasi-spiral structure in deprojected density and temperature fields, delineated by a tangential discontinuity known…
Solvability of orbit-finite systems of linear equations
Arka Ghosh, Piotr Hofman, Sławomir Lasota
We study orbit-finite systems of linear equations, in the setting of sets with atoms. Our principal contribution is a decision procedure for solvability of such systems. The proced…
Nonlinear electromagnetic-wave interactions in pair plasma: (I) Non-relativistic regime
Arka Ghosh, Daniel Kagan, Uri Keshet +1
This paper is the first in a series devoted to the numerical study of nonlinear interactions of electromagnetic waves with plasma. We start with non-magnetized pair plasmas, where…
