Dimension-independent likelihood-informed MCMC
Tiangang Cui, Kody J. H. Law, Youssef M. Marzouk
Many Bayesian inference problems require exploring the posterior distribution of high-dimensional parameters that represent the discretization of an underlying function. This work…
Controlling Unpredictability with Observations in the Partially Observed Lorenz '96 Model
K. J. H. Law, D. Sanz-Alonso, A. Shukla +1
In the context of filtering chaotic dynamical systems it is well-known that partial observations, if sufficiently informative, can be used to control the inherent uncertainty due t…
Deterministic Mean-field Ensemble Kalman Filtering
Kody J. H. Law, Hamidou Tembine, Raul Tempone
The proof of convergence of the standard ensemble Kalman filter (EnKF) from Legland etal. (2011) is extended to non-Gaussian state space models. A density-based deterministic appro…
Dynamic and Energetic Stabilization of Persistent Currents in Bose-Einstein Condensates
K. J. H. Law, T. W. Neely, P. G. Kevrekidis +3
We study conditions under which vortices in a highly oblate harmonically trapped Bose-Einstein condensate (BEC) can be stabilized due to pinning by a blue-detuned Gaussian laser be…
