A statistical and computational theory for robust and sparse Kalman smoothing
Aleksandr Y. Aravkin, James V. Burke, Gianluigi Pillonetto
Kalman smoothers reconstruct the state of a dynamical system starting from noisy output samples. While the classical estimator relies on quadratic penalization of process deviation…
Student's T Robust Bundle Adjustment Algorithm
Aleksandr Y. Aravkin, Michael Styer, Zachary Moratto +2
Bundle adjustment (BA) is the problem of refining a visual reconstruction to produce better structure and viewing parameter estimates. This problem is often formulated as a nonline…
Robust inversion via semistochastic dimensionality reduction
Aleksandr Aravkin, Michael P. Friedlander, Tristan van Leeuwen
We consider a class of inverse problems where it is possible to aggregate the results of multiple experiments. This class includes problems where the forward model is the solution…
