Numerically robust Gaussian state estimation with singular observation noise
Nicholas Krämer, Filip Tronarp
This article proposes numerically robust algorithms for Gaussian state estimation with singular observation noise. Our approach combines a series of basis changes with Bayes' rule,…

The two filter formula reconsidered: Smoothing in partially observed Gauss--Markov models without information parametrization
Filip Tronarp
In this article, the two filter formula is re-examined in the setting of partially observed Gauss--Markov models. It is traditionally formulated as a filter running backward in tim…
