Online learning with exponential weights in metric spaces
Quentin Paris
This paper addresses the problem of online learning in metric spaces using exponential weights. We extend the analysis of the exponentially weighted average forecaster, traditional…
Jensen's inequality in geodesic spaces with lower bounded curvature
Quentin Paris
Let be a separable and complete geodesic space with curvature lower bounded, by , in the sense of Alexandrov. Let be a Borel probability measure on ,…
The exponentially weighted average forecaster in geodesic spaces of non-positive curvature
Quentin Paris
This paper addresses the problem of prediction with expert advice for outcomes in a geodesic space with non-positive curvature in the sense of Alexandrov. Via geometric considerati…
On the occupancy problem for a regime switching model
Michael Grabchak, Mark Kelbert, Quentin Paris
This article studies the expected occupancy probabilities on an alphabet. Unlike the standard situation, where observations are assumed to be independent and identically distribute…
Convergence rates for empirical barycenters in metric spaces: curvature, convexity and extendible geodesics
Adil Ahidar-Coutrix, Thibaut Le Gouic, Quentin Paris
This paper provides rates of convergence for empirical (generalised) barycenters on compact geodesic metric spaces under general conditions using empirical processes techniques. Ou…
