Convergence of uncertainty estimates in Ensemble and Bayesian sparse model discovery

no code implementations30 Jan 2023 L. Mars Gao, Urban Fasel, Steven L. Brunton, J. Nathan Kutz

In the sparse model discovery experiment, we show that the bootstrapping-based sequential thresholding least-squares method can provide valid uncertainty quantification, converging to a delta measure centered around the true value with increased sample sizes.

Bayesian autoencoders for data-driven discovery of coordinates, governing equations and fundamental constants

no code implementations19 Nov 2022 L. Mars Gao, J. Nathan Kutz

Recent progress in autoencoder-based sparse identification of nonlinear dynamics (SINDy) under $\ell_1$ constraints allows joint discoveries of governing equations and latent coordinate systems from spatio-temporal data, including simulated video frames.
