Accelerated Sparse Recovery via Gradient Descent with Nonlinear Conjugate Gradient Momentum
Mengqi Hu, Yifei Lou, Bao Wang +3
This paper applies an idea of adaptive momentum for the nonlinear conjugate gradient to accelerate optimization problems in sparse recovery. Specifically, we consider two types of…

A Lifted Framework for Sparse Recovery
Yaghoub Rahimi, Sung Ha Kang, Yifei Lou
Motivated by re-weighted approaches for sparse recovery, we propose a lifted (LL1) regularization which is a generalized form of several popular regularizations i…

An Efficient Smoothing and Thresholding Image Segmentation Framework with Weighted Anisotropic-Isotropic Total Variation
Kevin Bui, Yifei Lou, Fredrick Park +1
In this paper, we design an efficient, multi-stage image segmentation framework that incorporates a weighted difference of anisotropic and isotropic total variation (AITV). The seg…
