International audience; Recent contributions to change-point detection, segmentation and inference for non-regular models are presented. Various problems are considered including the multiple change-point estimation with adaptive penalty for time ser

High-dimensional change-point detection under sparse alternatives

Autor: Farida Enikeeva, Zaid Harchaoui

Publikováno v: Ann. Statist. 47, no. 4 (2019), 2051-2079

We consider the problem of detecting a change in mean in a sequence of high-dimensional Gaussian vectors. The change in mean may be occurring simultaneously in an unknown subset components. We propose a hypothesis test to detect the presence of a cha

Bump detection in the presence of dependency: Does it ease or does it load?

Autor: Farida Enikeeva, Axel Munk, Frank Werner, Markus Pohlmann

Publikováno v: Bernoulli 26, no. 4 (2020), 3280-3310

We provide the asymptotic minimax detection boundary for a bump, i.e. an abrupt change, in the mean function of a stationary Gaussian process. This will be characterized in terms of the asymptotic behavior of the bump length and height as well as the

Restriction–modification systems and bacteriophage invasion: Who wins?

Autor: Mikhail S. Gelfand, Farida Enikeeva, Konstantin Severinov

Publikováno v: Journal of Theoretical Biology. 266:550-559

The success of a phage that infects a bacterial cell possessing a restriction-modification (R-M) system depends on the activities of the host methyltransferase and restriction endonuclease, and the number of susceptible sites in the phage genome. How

Empirical bayesian test of the smoothness

Autor: Eduard Belitser, Farida Enikeeva

Publikováno v: Mathematical Methods of Statistics, 17(1), 1-18. Allerton Press Inc.

In the context of adaptive nonparametric curve estimation a common assumption is that a function (signal) to estimate belongs to a nested family of functional classes. These classes are often parametrized by a quantity representing the smoothness of

Bump detection in heterogeneous Gaussian regression

Bernoulli

We analyze the effect of a heterogeneous variance on bump detection in a Gaussian regression model. To this end we allow for a simultaneous bump in the variance and specify its impact on the difficulty to detect the null signal against a single bump

On the Minimax Estimation Problem of a Fractional Derivative

Autor: Farida Enikeeva, G. G. Golubev

Publikováno v: Theory of Probability & Its Applications. 46:619-635

We consider the problem of minimax estimating the fractional derivative of the order~$-\frac{1}{2}$ of an unknown function in the Gaussian white noise model. This problem is closely related to the well-known Wicksell problem. In this paper the second

Continuity Estimates for Ruin Probabilities

Autor: Vladimir Viacheslavovich Kalashnikov, Farida Enikeeva, Deimante Rusaityte

Publikováno v: Scandinavian Actuarial Journal. 2001:18-39

A method of continuity analysis of ruin probabilities with respect to variation of parameters governing risk processes is proposed. It is based on the representation of the ruin probability as the stationary probability of a reversed process. We appl

[Untitled]

Autor: Farida Enikeeva, G. K. Golubev

Publikováno v: Problems of Information Transmission. 37:24-45

In the Wicksell problem, it is required to reconstruct a distribution function of radii of balls located in an opaque medium from measurements of radii of circles obtained by intersecting the medium with a certain plane. This problem is intimately bo
