Correcting observation model error in data assimilation

CHAOS, 29(5).

By: F. Hamilton n, T. Berry n & T. Sauer n

TL;DR: This work proposes a method for observation model error correction within the filtering framework that involves an alternating minimization algorithm used to iteratively update a given observation function to increase consistency with the model and prior observations using ideas from attractor reconstruction.

Nonlinear Kalman filtering for censored observations

Applied Mathematics and Computation, 316, 155–166.

By: J. Arthur*, A. Attarian*, F. Hamilton n & H. Tran n

author keywords: Extended Kalman filter; Censored observation; Parameter estimation; Hepatitis C virus (HCV); Human immunodeficiency virus (HIV)
TL;DR: A modified version of the extended Kalman filter is developed to handle the case of censored observations in nonlinear systems and is validated in a simple oscillator system first, showing its ability to accurately reconstruct state variables and track system parameters when observations are censored.

Kalman-Takens filtering in the presence of dynamical noise

EUROPEAN PHYSICAL JOURNAL-SPECIAL TOPICS, 226(15), 3239–3250.

By: F. Hamilton n, T. Berry* & T. Sauer*

TL;DR: By combining the Kalman-Takens method with an adaptive filtering procedure, the statistics of the observational and dynamical noise are estimated and this solves a long-standing problem of separating dynamical and observational noise in time series data. (via Semantic Scholar)
