Fast algorithms for hyperspectral Diffuse Optical Tomography
Arvind K. Saibaba, Misha Kilmer, Eric Miller +1
The image reconstruction of chromophore concentrations using Diffuse Optical Tomography (DOT) data can be described mathematically as an ill-posed inverse problem. Recent work has…

Fast Kalman Filter using Hierarchical-matrices and low-rank perturbative approach
Arvind K. Saibaba, Eric Miller, Peter K. Kitanidis
We develop a fast algorithm for Kalman Filter applied to the random walk forecast model. The key idea is an efficient representation of the estimate covariance matrix at each time-…
