Take It or Leave It: Intent-Controlled Partial Optimal Transport

Salil Parth Tripathi, Bertrand Chapron, Fabrice Collard +2

While optimal transport (OT) enforces a rigid constraint by requiring two measures to be matched exactly, partial optimal transport relaxes this requirement by allowing mass to rem…

Online Calibration of Deep Learning Sub-Models for Hybrid Numerical Modeling Systems

Said Ouala, Bertrand Chapron, Fabrice Collard +2

Artificial intelligence and deep learning are currently reshaping numerical simulation frameworks by introducing new modeling capabilities. These frameworks are extensively investi…

Bounded nonlinear forecasts of partially observed geophysical systems with physics-constrained deep learning

Said Ouala, Steven L. Brunton, Ananda Pascual +4

The complexity of real-world geophysical systems is often compounded by the fact that the observed measurements depend on hidden variables. These latent variables include unresolve…

Exploitation of error correlation in a large analysis validation: GlobCurrent case study

Richard E. Danielson, Johnny A. Johannessen, Graham D. Quartly +4

An assessment of variance in ocean current signal and noise shared by in situ observations (drifters) and a large gridded analysis (GlobCurrent) is sought as a function of day of t…

Learning Runge-Kutta Integration Schemes for ODE Simulation and Identification

Said Ouala, Laurent Debreu, Ananda Pascual +4

Deriving analytical solutions of ordinary differential equations is usually restricted to a small subset of problems and numerical techniques are considered. Inevitably, a numerica…

Learning Latent Dynamics for Partially-Observed Chaotic Systems

Said Ouala, Duong Nguyen, Lucas Drumetz +5

This paper addresses the data-driven identification of latent dynamical representations of partially-observed systems, i.e., dynamical systems for which some components are never o…
