Construction of Hierarchically Semi-Separable matrix Representation using Adaptive Johnson-Lindenstrauss Sketching
Yotam Yaniv, Pieter Ghysels, Osman Asif Malik +2
We present an extension of an adaptive, partially matrix-free, Hierarchically Semi-Separable (HSS) matrix construction algorithm by Gorman et al. [SIAM J. Sci. Comput. 41(5), 2019]…
Multi-Randomized Kaczmarz for Latent Class Regression
Erin George, Yotam Yaniv, Deanna Needell
Linear regression is effective at identifying interpretable trends in a data set, but averages out potentially different effects on subgroups within data. We propose an iterative a…
Online Signal Recovery via Heavy Ball Kaczmarz
Benjamin Jarman, Yotam Yaniv, Deanna Needell
Recovering a signal from a sequence of linear measurements is an important problem in areas such as computerized tomography and compressed sensing. In thi…
Selectable Set Randomized Kaczmarz
Yotam Yaniv, Jacob D. Moorman, William Swartworth +3
The Randomized Kaczmarz method (RK) is a stochastic iterative method for solving linear systems that has recently grown in popularity due to its speed and low memory requirement. S…
Modeling Environmental Crime in Protected Areas Using the Level Set Method
David J. Arnold, Dayne Fernandez, Ruizhe Jia +5
National parks often serve as hotspots for environmental crime such as illegal deforestation and animal poaching. Previous attempts to model environmental crime were either discret…
