Alsvinn: A Fast multi-GPGPU finite volume solver with a strong emphasis on reproducibility
Kjetil Lye
We present the Alsvinn simulator, a fast multi general purpose graphical processing unit (GPGPU) finite volume solver for hyperbolic conservation laws in multiple space dimensions.…
A Multi-level procedure for enhancing accuracy of machine learning algorithms
Kjetil O. Lye, Siddhartha Mishra, Roberto Molinaro
We propose a multi-level method to increase the accuracy of machine learning algorithms for approximating observables in scientific computing, particularly those that arise in syst…
Statistical solutions of hyperbolic systems of conservation laws: numerical approximation
Ulrik Skre Fjordholm, Kjetil Lye, Siddhartha Mishra +1
Statistical solutions are time-parameterized probability measures on spaces of integrable functions, that have been proposed recently as a framework for global solutions and uncert…
Deep learning observables in computational fluid dynamics
Kjetil O. Lye, Siddhartha Mishra, Deep Ray
Many large scale problems in computational fluid dynamics such as uncertainty quantification, Bayesian inversion, data assimilation and PDE constrained optimization are considered…
