Correcting observation model error in data assimilation
CHAOS, 29(5).
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.

Kalman-Takens filtering in the presence of dynamical noise
EUROPEAN PHYSICAL JOURNAL-SPECIAL TOPICS, 226(15), 3239–3250.
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.

Nonlinear Kalman filtering for censored observations
Applied Mathematics and Computation, 316, 155–166.
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.
