ADOM: ADMM-Based Optimization Model for Stripe Noise Removal in Remote Sensing Image
IEEE Access, 2023 Remote sensing images (RSI) are useful for various tasks such as Earth observation and climate change. However, RSI may suffer from stripe noise due to physical limitations in sensor systems.

DQM: Decentralized Quadratically Approximated Alternating Direction Method of Multipliers [PDF]
IEEE Transactions on Signal Processing, 2015 This paper considers an optimization problem that components of the objective function are available at different nodes of a network and nodes are allowed to only exchange information with their neighbors. The decentralized alternating method of multipliers (DADMM) is a well-established iterative method for solving this category of problems; however ...

Quasistatic cohesive fracture with an alternating direction method of multipliers [PDF]
Engineering Fracture Mechanics, 2022 A method for quasistatic cohesive fracture is introduced that uses an alternating direction method of multipliers (ADMM) to implement an energy approach to cohesive fracture. The ADMM algorithm minimizes a non-smooth, non-convex potential functional at each strain increment to predict the evolution of a cohesive-elastic system. The optimization problem

A fully distributed method for distributed multiagent system in a microgrid
Energy Reports, 2021 We address the distributed energy management problem of the economic dispatch of grids in order to balance the power demand and supply. By manipulating the primal problem, we show that the resulting dual problem can be solved by using a decentralized ...

A Proximal Alternating Direction Method of Multipliers with a Substitution Procedure [PDF]
Mathematical Problems in Engineering, 2020 In this paper, we considers the separable convex programming problem with linear constraints. Its objective function is the sum of m individual blocks with nonoverlapping variables and each block consists of two functions: one is smooth convex and the other one is convex.

On Convergence Rates of Proximal Alternating Direction Method of Multipliers
Journal of Scientific Computing, 2023 AbstractIn this paper we consider from two different aspects the proximal alternating direction method of multipliers (ADMM) in Hilbert spaces. We first consider the application of the proximal ADMM to solve well-posed linearly constrained two-block separable convex minimization problems in Hilbert spaces and obtain new and improved non-ergodic ...

Alternating Direction Method of Multiplier for Tomography With Nonlocal Regularizers [PDF]
IEEE Transactions on Medical Imaging, 2014 The ordered subset expectation maximization (OSEM) algorithm approximates the gradient of a likelihood function using a subset of projections instead of using all projections so that fast image reconstruction is possible for emission and transmission tomography such as SPECT, PET, and CT.
