FunQuant: A R package to perform quantization in the context of rare events and time-consuming simulations
Charlie Sire, Yann Richet, Rodolphe Le Riche +3
Quantization summarizes continuous distributions by calculating a discrete approximation. Among the widely adopted methods for data quantization is Lloyd's algorithm, which partiti…
Quantizing rare random maps: application to flooding visualization
Charlie Sire, Rodolphe Le Riche, Didier Rullière +3
Visualization is an essential operation when assessing the risk of rare events such as coastal or river floodings. The goal is to display a few prototype events that best represent…
Statistical estimation of spatial wave extremes for tropical cyclones from small data samples: validation of the STM-E approach using long-term synthetic cyclone data for the Caribbean Sea
Ryota Wada, Jeremy Rohmer, Yann Krien +1
Occurrences of tropical cyclones at a location are rare, and for many locations, only short periods of observations or hindcasts are available. Hence, estimation of return values (…
Multioutput Gaussian Processes with Functional Data: A Study on Coastal Flood Hazard Assessment
A. F. López-Lopera, D. Idier, J. Rohmer +1
Surrogate models are often used to replace costly-to-evaluate complex coastal codes to achieve substantial computational savings. In many of those models, the hydrometeorological f…
Functional principal component analysis for global sensitivity analysis of model with spatial output
T. V. E. Perrin, O. Roustant, J. Rohmer +6
Motivated by risk assessment of coastal flooding, we consider time-consuming simulators with a spatial output. The aim is to perform sensitivity analysis (SA), quantifying the infl…
Profile extrema for visualizing and quantifying uncertainties on excursion regions. Application to coastal flooding
Dario Azzimonti, David Ginsbourger, Jérémy Rohmer +1
We consider the problem of describing excursion sets of a real-valued function , i.e. the set of inputs where is above a fixed threshold. Such regions are hard to visualize…
