Conic reach and polynomial parallel volume in the plane
Alejandro Cholaquidis
For a compact set , the local Steiner formula of Hug, Last and Weil expresses the parallel volume through the proximal normal bundle and the truncated fiber…
Concave Statistical Utility Maximization Bandits via Influence-Function Gradients
Matías Carrasco, Alejandro Cholaquidis
We study stochastic multi-armed bandits in which the objective is a statistical functional of the long-run reward distribution, rather than expected reward alone. Under mild contin…
Conformal Robust Set Estimation
Alejandro Cholaquidis, Emilien Joly, Leonardo Moreno
We introduce a robust conformal prediction method based on the half-mass radius $\dP(x):=\inf\{r>0:P(B(x,r))>1/2\}$. Its empirical version is exactly the distance from a point to i…
Weak convergence from projected laws on a positive-measure set of directions
Alejandro Cholaquidis, Manuel Hernández-Banadik
The Cramér-Wold device characterises weak convergence of probability measures on through convergence of all one-dimensional projected laws. We prove that, if the tar…
A bootstrap approach for testing invariance under parameterized group actions: orthogonal reflections and axial symmetry
Alejandro Cholaquidis, Juan Cuesta-Albertos, Ricardo Fraiman +1
Testing whether a multivariate distribution is invariant under an orthogonal transformation is a classical problem when the transformation is fixed in advance. We address a harder…
