Robust and Simple ADMM Penalty Parameter Selection

Autor: MICHAEL T. MCCANN, Brendt Wohlberg

Publikováno v: IEEE Open Journal of Signal Processing, Vol 5, Pp 402-420 (2024)

We present a new method for online selection of the penalty parameter for the alternating direction method of multipliers (ADMM) algorithm. ADMM is a widely used method for solving a range of optimization problems, including those that arise in signa

Publikováno v: IEEE Transactions on Computational Imaging. 9:314-326

We propose a method for performing material identification from radiographs without energy-resolved measurements. Material identification has a wide variety of applications, including in biomedical imaging, nondestructive testing, and security. While

Research Summary: The optimal distinctiveness literature highlights a fundamental trade-off in product positioning within market categories: Products should be distinct to minimize competition, but similar to build legitimacy. Most recently, this res

Publikováno v: Journal of the American Chemical Society. 144:13050-13054

Fluorescence microscopy with fluorescent reporters that respond to environmental cues is a powerful method for interrogating biochemistry and biophysics in living systems. Photoinduced electron transfer (PeT) is commonly used as a trigger to modulate
