Affine Invariant Langevin Dynamics for rare-event sampling
Deepyaman Chakraborty, Ruben Harris, Rupert Klein +3
We introduce an affine invariant Langevin dynamics (ALDI) framework for the efficient estimation of rare events in nonlinear dynamical systems. Rare events are formulated as Bayesi…

Accuracy Boost in Ensemble Kalman Inversion via Ensemble Control Strategies
Ruben Harris, Claudia Schillings
The Ensemble Kalman Inversion (EKI) method is widely used for solving inverse problems, leveraging ensemble-based techniques to iteratively refine parameter estimates. Despite its…
