Moderate deviations via cumulants
, 2010 The purpose of the present paper is to establish moderate deviation principles for a rather general class of random variables fulfilling certain bounds of the cumulants.

Statistical Characteristics of Basal Forces Generated by Experimental Debris Flows
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 3, March 2025.Abstract Debris flows are fast‐flowing, high‐energy mixtures of sediment and water that are difficult to monitor. Seismic monitoring instruments can be placed safely outside the channel, but it is an indirect method that needs the application of theory‐based inversion to obtain quantitative information on flow properties and rheology.

Scaling-up Empirical Risk Minimization: Optimization of Incomplete U-statistics [PDF]
, 2016 In a wide range of statistical learning problems such as ranking, clustering or metric learning among others, the risk is accurately estimated by $U$-statistics of degree $d\geq 1$, i.e.

Packing spanning graphs from separable families
, 2016 Let $\mathcal G$ be a separable family of graphs. Then for all positive constants $\epsilon$ and $\Delta$ and for every sufficiently large integer $n$, every sequence $G_1,\dotsc,G_t\in\mathcal G$ of graphs of order $n$ and maximum degree at most $\Delta$

Goodness‐of‐fit testing based on graph functionals for homogeneous Erdös–Rényi graphs
Scandinavian Journal of Statistics, Volume 52, Issue 1, Page 332-380, March 2025.Abstract The Erdös–Rényi graph is a popular choice to model network data as it is parsimoniously parameterized, straightforward to interpret and easy to estimate. However, it has limited suitability in practice, since it often fails to capture crucial characteristics of real‐world networks. To check its adequacy, we propose a novel class of goodness‐of‐

Limit theorems for von Mises statistics of a measure preserving transformation
, 2014 For a measure preserving transformation $T$ of a probability space $(X,\mathcal F,\mu)$ we investigate almost sure and distributional convergence of random variables of the form $$x \to \frac{1}{C_n} \sum_ ...

A Correctness Result for Online Robust PCA
, 2015 This work studies the problem of sequentially recovering a sparse vector $x_t$ and a vector from a low-dimensional subspace $l_t$ from knowledge of their sum $m_t = x_t + l_t$. If the primary goal is to recover the low-dimensional subspace where the $l_t$

Estimation of a regular conditional functional by conditional U‐statistic regression
Statistica Neerlandica, Volume 79, Issue 1, February 2025.U‐statistics constitute a large class of estimators, generalizing the empirical mean of a random variable X to sums over every k‐tuple of distinct observations of X. They may be used to estimate a regular functional θ(ℙX) of the law of X. When a vector of covariates Z is available, a conditional U‐statistic describes the effect of z on the conditional ...

Applied Stochastic Models in Business and Industry, Volume 41, Issue 1, January/February 2025.ABSTRACT Negative probabilities arise primarily in physics, statistical quantum mechanics, and quantum computing. Negative probabilities arise as mixing distributions of unobserved latent variables in Bayesian modeling. Our goal is to provide a link between these two viewpoints.

, 2010 The notion of a $U$-statistic for an $n$-tuple of identical quantum systems is introduced in analogy to the classical (commutative) case: given a selfadjoint `kernel' $K$ acting on $(\mathbb{C}^{d})^{\otimes r}$ with ...
