Linear Convergence of Stochastic Iterative Greedy Algorithms with Sparse Constraints
Nam Nguyen, Deanna Needell, Tina Woolf
Motivated by recent work on stochastic gradient descent methods, we develop two stochastic variants of greedy algorithms for possibly non-convex optimization problems with sparsity…
A Comparison of Clustering and Missing Data Methods for Health Sciences
Ran Zhao, Deanna Needell, Christopher Johansen +1
In this paper, we compare and analyze clustering methods with missing data in health behavior research. In particular, we propose and analyze the use of compressive sensing's matri…
Randomized Block Kaczmarz Method with Projection for Solving Least Squares
Deanna Needell, Ran Zhao, Anastasios Zouzias
The Kaczmarz method is an iterative method for solving overcomplete linear systems of equations Ax=b. The randomized version of the Kaczmarz method put forth by Strohmer and Vershy…
