An entropic analogue of the MMS conjecture

Jianhang Ai, Ondřej Kuželka, Christos Pelekis

Let $P = {x_{1}, \dots, x_{n}}$ be a multiset consisting of $n \geq 2$ real numbers such that $\sum_{i = 1}^{n} x_{i} = 0$ and $\sum_{i = 1}^{n} ∣ x_{i} ∣ > 0$ , and let $k < n$ be a positive integer. We s…

Concentration inequalities for the sum in sampling without replacement: an approach via majorization

Jianhang Ai, Ondřej Kuželka, Christos Pelekis

Let $P = (x_{1}, \dots, x_{n})$ be a population consisting of $n \geq 2$ real numbers whose sum is zero, and let $k < n$ be a positive integer. We sample $k$ elements from $P$ without replac…

Faster Repeated Evasion Attacks in Tree Ensembles

Lorenzo Cascioli, Laurens Devos, Ondřej Kuželka +1

Tree ensembles are one of the most widely used model classes. However, these models are susceptible to adversarial examples, i.e., slightly perturbed examples that elicit a mispred…

Jump-Diffusion Langevin Dynamics for Multimodal Posterior Sampling

Jacopo Guidolin, Vyacheslav Kungurtsev, Ondřej Kuželka

Bayesian methods of sampling from a posterior distribution are becoming increasingly popular due to their ability to precisely display the uncertainty of a model fit. Classical met…
