Ensemble Principal Component Analysis
Olga Dorabiala, Aleksandr Aravkin, J. Nathan Kutz
Efficient representations of data are essential for processing, exploration, and human understanding, and Principal Component Analysis (PCA) is one of the most common dimensionalit…
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 and Trend-following Kalman Smoothers using Student's t
Aleksandr Y. Aravkin, James V. Burke, Gianluigi Pillonetto
We propose two nonlinear Kalman smoothers that rely on Student's t distributions. The T-Robust smoother finds the maximum a posteriori likelihood (MAP) solution for Gaussian proces…
