Mol-CycleGAN - a generative model for molecular optimization

Autor: Maziarka, Łukasz, Pocha, Agnieszka, Kaczmarczyk, Jan, Rataj, Krzysztof, Warchoł, Michał

Publikováno v: Journal of Cheminformatics 12, 2 (2020)

Designing a molecule with desired properties is one of the biggest challenges in drug development, as it requires optimization of chemical compound structures with respect to many complex properties. To augment the compound design process we introduc

Nonparametric estimation of extremal dependence

Autor: Kiriliouk, Anna, Segers, Johan, Warchol, Michal

There is an increasing interest to understand the dependence structure of a random vector not only in the center of its distribution but also in the tails. Extreme-value theory tackles the problem of modelling the joint tail of a multivariate distrib

Statistics for Tail Processes of Markov Chains

Autor: Drees, Holger, Segers, Johan, Warchoł, Michał

At high levels, the asymptotic distribution of a stationary, regularly varying Markov chain is conveniently given by its tail process. The latter takes the form of a geometric random walk, the increment distribution depending on the sign of the proce

A Euclidean likelihood estimator for bivariate tail dependence

Autor: de Carvalho, Miguel, Oumow, Boris, Segers, Johan, Warchoł, Michał

The spectral measure plays a key role in the statistical modeling of multivariate extremes. Estimation of the spectral measure is a complex issue, given the need to obey a certain moment condition. We propose a Euclidean likelihood-based estimator fo
