Spatial-temporal switching estimators for imaging locally concentrated dynamics

no code implementations19 Feb 2021 Parisa Karimi, Mark Butala, Zhizhen Zhao, Farzad Kamalabadi

The evolution of images with physics-based dynamics is often spatially localized and nonlinear.

Efficient model selection in switching linear dynamic systems by graph clustering

no code implementations8 Dec 2020 Parisa Karimi, Mark Butala, Zhizhen Zhao, Farzad Kamalabadi

The computation required for a switching Kalman Filter (SKF) increases exponentially with the number of system operation modes.

Quantification of mismatch error in randomly switching linear state-space models

no code implementations8 Dec 2020 Parisa Karimi, Zhizhen Zhao, Mark Butala, Farzad Kamalabadi

One can use these derivations to quantify the average performance of filters beforehand and decide which filter to run in operation to have the best performance in terms of estimation error and computation complexity.
