Regression modeling of multivariate precipitation extremes under regular variation
Rishikesh Yadav, Arnab Hazra
Motivated by the EVA2025 data challenge, where we participated as the team DesiBoys, we propose a regression strategy within the framework of regular variation to estimate the occu…
Scalable Spatiotemporal Modeling for Bicycle Count Prediction
Rishikesh Yadav, Alexandra M. Schmidt, Aurelie Labbe +2
We propose a novel sparse spatiotemporal dynamic generalized linear model for efficient inference and prediction of bicycle count data. Assuming Poisson distributed counts with spa…
Approximation of the Koopman operator via Bernstein polynomials
Rishikesh Yadav, Alexandre Mauroy
The Koopman operator approach provides a powerful linear description of nonlinear dynamical systems in terms of the evolution of observables. While the operator is typically infini…
An utopic adventure in the modelling of conditional univariate and multivariate extremes
Léo R. Belzile, Arnab Hazra, Rishikesh Yadav
The EVA 2023 data competition consisted of four challenges, ranging from interval estimation for very high quantiles of univariate extremes conditional on covariates, point estimat…
