Agglomerative Clustering with Threshold Optimization via Extreme Value Theory
Algorithms, 2022 Clustering is a critical part of many tasks and, in most applications, the number of clusters in the data are unknown and must be estimated. This paper presents an Extreme Value Theory-based approach to threshold selection for clustering, proving that ...

Extreme Value Theory and the Solar Cycle [PDF]
, 2007 We investigate the statistical properties of the extreme events of the solar cycle as measured by the sunspot number. The recent advances in the methodology of the theory of extreme values is applied to the maximal extremes of the time series of sunspots.

Bridge Damage Detection Using Complexity Pursuit and Extreme Value Theory
Buildings, 2023 Bridge structures are susceptible to environmental and operational variations (EOVs). Improperly handling these influences may result in incorrect assessments of the bridge’s health condition.

Extreme events in total ozone over Arosa – Part 1: Application of extreme value theory [PDF]
Atmospheric Chemistry and Physics, 2010 In this study ideas from extreme value theory are for the first time applied in the field of stratospheric ozone research, because statistical analysis showed that previously used concepts assuming a Gaussian distribution (e.g. fixed deviations from mean

, 2019 AbstractFrom travel disruptions to natural disasters, extreme events have long captured the public’s imagination and attention. Due to their rarity and often associated calamity, they make waves in the news (Fig. 3.1) and stir discussion in the public realm: is it a freak event? Events of this sort may be shrouded in mystery for the general public, but

, 2009 Being the limits of copulas of componentwise maxima in independent random samples, extreme-value copulas can be considered to provide appropriate models for the dependence structure between rare events.

Sampling local properties of attractors via Extreme Value Theory [PDF]
, 2014 We provide formulas to compute the coefficients entering the affine scaling needed to get a non-degenerate function for the asymptotic distribution of the maxima of some kind of observable computed along the orbit of a randomly perturbed dynamical system.

Weibull-Open-World (WOW) Multi-Type Novelty Detection in CartPole3D
Algorithms, 2022 Algorithms for automated novelty detection and management are of growing interest but must address the inherent uncertainty from variations in non-novel environments while detecting the changes from the novelty.

Extreme value theory applied to the millennial sunspot number series [PDF]
, 2018 In this work, we use two decadal sunspot number series reconstructed from cosmogenic radionuclide data (14C in tree trunks, SN-14C and 10Be in polar ice, SN-10Be) and the Extreme Value Theory to study variability of solar activity during the last 9 ...
