Time-uniform accuracy of ensemble Kalman filters with localization

Xiaoou Cheng, Daniel Sanz-Alonso, Nathan Waniorek

This paper establishes time-uniform accuracy guarantees for deterministic square-root ensemble Kalman filters in linear--Gaussian state-space models under perfect-model dynamics. F…

From Spectral Methods to Sample Complexity Bounds for Fourier Neural Operators

Nisha Chandramoorthy, Daniel Sanz-Alonso, Nathan Waniorek

We establish approximation and learning guarantees for Fourier neural operators (FNOs) applied to time- solution operators of dissipative evolution equations. The analysis build…
