A Proof of Principle: Multi-Modality Radiotherapy Optimization
Roman Levin, Aleksandr Y. Aravkin, Minsun Kim
Radiotherapy is used to treat cancer patients by damaging DNA of tumor cells using ionizing radiation. Photons are the most widely used radiation type for therapy, having been put…
Dimensionality Reduction and Reduced Order Modeling for Traveling Wave Physics
Ariana Mendible, Steven L. Brunton, Aleksandr Y. Aravkin +2
We develop an unsupervised machine learning algorithm for the automated discovery and identification of traveling waves in spatio-temporal systems governed by partial differential…
Efficient Robust Parameter Identification in Generalized Kalman Smoothing Models
Jonathan Jonker, Peng Zheng, Aleksandr Y. Aravkin
Dynamic inference problems in autoregressive (AR/ARMA/ARIMA), exponential smoothing, and navigation are often formulated and solved using state-space models (SSM), which allow a ra…
IRLS for Sparse Recovery Revisited: Examples of Failure and a Remedy
Aleksandr Y. Aravkin, James V. Burke, Daiwei He
Compressed sensing is a central topic in signal processing with myriad applications, where the goal is to recover a signal from as few observations as possible. Iterative re-weight…
Trimmed Constrained Mixed Effects Models: Formulations and Algorithms
Peng Zheng, Ryan Barber, Reed J. D. Sorensen +2
Mixed effects (ME) models inform a vast array of problems in the physical and social sciences, and are pervasive in meta-analysis. We consider ME models where the random effects co…
Preliminary Results in Current Profile Estimation and Doppler-aided Navigation for Autonomous Underwater Gliders
Jonathan Jonker, Andrey Shcherbina, Richard Krishfield +3
This paper describes the development and experimental results of navigation algorithms for an autonomous underwater glider (AUG) that uses an on-board acoustic Doppler current prof…
