Stochastic Control of Addiction with State-Dependent Jump Relapse
Dounia Aissi, Ioana Ciotir, Dan Goreac +1
We study a continuous-time rational addiction model where addiction capital follows a piecewise deterministic Markov process with state-dependent jumps capturing relapse and recove…
Complexity reduction in online stochastic Newton methods with potential O(N d) total cost
Antoine Godichon-Baggioni, Bruno Portier, Guillaume Sallé
Optimizing smooth convex functions in stochastic settings, where only noisy estimates of gradients and Hessians are available, is a fundamental problem in optimization. While first…
Geographically Weighted Regression for Air Quality Low-Cost Sensor Calibration
Jean-Michel Poggi, Bruno Portier, Emma Thulliez
This article focuses on the use of Geographically Weighted Regression (GWR) method to correct air quality low-cost sensors measurements. Those sensors are of major interest in the…
Using low-cost sensors to improve NO2 concentration maps derived from physico-chemical models
Emma Thulliez, Camille Coron
Urban air quality is a major concern today. Concentrations of pollutants, such as nitrogen dioxide, must be monitored to ensure that they do not exceed hazardous thresholds. For th…
Debiasing physico-chemical models in air quality monitoring by combining different pollutant concentration measures
Benjamin Auder, Camille Coron, Jean-Michel Poggi +1
Air quality monitoring requires to produce accurate estimation of nitrogen dioxide or fine particulate matter concentration maps, at different moments. A typical strategy is to com…
Beyond uniqueness: Relaxation calculus of junction conditions for coercive Hamilton-Jacobi equations
Nicolas Forcadel, Regis Monneau
A junction is a particular network given by the collection of half lines glued together at the origin. On such a junction, we consider evolutive Hamilton-Jac…
