Theoretical Advances in Current Estimation and Navigation from a Glider-Based Acoustic Doppler Current Profiler (ADCP)
Jacob Stevens-Haas, Sarah E. Webster, Aleksandr Aravkin
We examine acoustic Doppler current profiler (ADCP) measurements from underwater gliders to determine glider position, glider velocity, and subsurface current. ADCPs, however, do n…
Analysis and Methods to Mitigate Effects of Under-reporting in Count Data
Jennifer Brennan, Marlena Bannick, Nicholas Kassebaum +4
Under-reporting of count data poses a major roadblock for prediction and inference. In this paper, we focus on the Pogit model, which deconvolves the generating Poisson process fro…
Robust Trimmed k-means
Olga Dorabiala, J. Nathan Kutz, Aleksandr Aravkin
Clustering is a fundamental tool in unsupervised learning, used to group objects by distinguishing between similar and dissimilar features of a given data set. One of the most comm…
Promoting global stability in data-driven models of quadratic nonlinear dynamics
Alan A. Kaptanoglu, Jared L. Callaham, Christopher J. Hansen +2
Modeling realistic fluid and plasma flows is computationally intensive, motivating the use of reduced-order models for a variety of scientific and engineering tasks. However, it is…
A hyperparameter-tuning approach to automated inverse planning
Kelsey Maass, Aleksandr Aravkin, Minsun Kim
Radiotherapy inverse planning often requires planners to modify parameters in the treatment planning system's objective function to produce clinically acceptable plans. Due to the…
l1-Norm Minimization with Regula Falsi Type Root Finding Methods
Metin Vural, Aleksandr Y. Aravkin, Sławomir Stan'czak
Sparse level-set formulations allow practitioners to find the minimum 1-norm solution subject to likelihood constraints. Prior art requires this constraint to be convex. In this le…
