Linear Convergence of Reshuffling Kaczmarz Methods With Sparse Constraints

Halyun Jeong, Deanna Needell

The Kaczmarz method (KZ) and its variants, which are types of stochastic gradient descent (SGD) methods, have been extensively studied due to their simplicity and efficiency in sol…

Federated Gradient Matching Pursuit

Halyun Jeong, Deanna Needell, Jing Qin

Traditional machine learning techniques require centralizing all training data on one server or data hub. Due to the development of communication technologies and a huge amount of…

NBIHT: An Efficient Algorithm for 1-bit Compressed Sensing with Optimal Error Decay Rate

Michael P. Friedlander, Halyun Jeong, Yaniv Plan +1

The Binary Iterative Hard Thresholding (BIHT) algorithm is a popular reconstruction method for one-bit compressed sensing due to its simplicity and fast empirical convergence. Ther…

Polar Deconvolution of Mixed Signals

Zhenan Fan, Halyun Jeong, Babhru Joshi +1

The signal demixing problem seeks to separate a superposition of multiple signals into its constituent components. This paper studies a two-stage approach that first decompresses a…

Approximate methods for phase retrieval via gauge duality

Ron Estrin, Yifan Sun, Halyun Jeong +1

We consider the problem of finding a low rank symmetric matrix satisfying a system of linear equations, as appears in phase retrieval. In particular, we solve the gauge dual formul…

Sub-Gaussian Matrices on Sets: Optimal Tail Dependence and Applications

Halyun Jeong, Xiaowei Li, Yaniv Plan +1

Random linear mappings are widely used in modern signal processing, compressed sensing and machine learning. These mappings may be used to embed the data into a significantly lower…

Polar Alignment and Atomic Decomposition

Zhenan Fan, Halyun Jeong, Yifan Sun +1

Structured optimization uses a prescribed set of atoms to assemble a solution that fits a model to data. Polarity, which extends the familiar notion of orthogonality from linear se…

Convergence of the randomized Kaczmarz method for phase retrieval

Halyun Jeong, C. Sinan Güntürk

The classical Kaczmarz iteration and its randomized variants are popular tools for fast inversion of linear overdetermined systems. This method extends naturally to the setting of…

Sparse Linear Representation

Halyun Jeong, Young-Han Kim

This paper studies the question of how well a signal can be reprsented by a sparse linear combination of reference signals from an overcomplete dictionary. When the dictionary size…
