The Fundamental Subspaces of
Ensemble Kalman Inversion

Elizabeth Qian (Georgia Tech) and Christopher Beattie (Virginia Tech)

This page contains interactive 3D visualizations of the fundamental subspaces of Ensemble Kalman Inversion described in our preprint for a fixed inverse problem and ensemble initialization (Qian & Beattie 2024).

Particle paths are plotted in light blue with conical arrowheads at the end of the path (note that in observation space they move in 1D in this example, but you can see the arrowheads clustered around the EKI solution). Toggle Stochastic/Deterministic Paths.

Note that the visualization seems to take a while to load on iOS for some reason.
