ADMM-SVNet: An ADMM-Based Sparse-View CT Reconstruction Network
Photonics, 2022 In clinical medical applications, sparse-view computed tomography (CT) imaging is an effective method for reducing radiation doses. The iterative reconstruction method is usually adopted for sparse-view CT.

ADMM-Softmax: an ADMM approach for multinomial logistic regression [PDF]
ETNA - Electronic Transactions on Numerical Analysis, 2020 We present ADMM-Softmax, an alternating direction method of multipliers (ADMM) for solving multinomial logistic regression (MLR) problems. Our method is geared toward supervised classification tasks with many examples and features. It decouples the nonlinear optimization problem in MLR into three steps that can be solved efficiently.

CoRR, 2022 We consider a class of Riemannian optimization problems where the objective is the sum of a smooth function and a nonsmooth function, considered in the ambient space. This class of problems finds important applications in machine learning and statistics such as the sparse principal component analysis, sparse spectral clustering, and orthogonal ...

Dynamic Sharing Through the ADMM [PDF]
IEEE Transactions on Automatic Control, 2020 In this paper, we study a dynamic version of the sharing problem, in which a dynamic system cost function composed of time-variant local costs of subsystems and a shared time-variant cost of the whole system is minimized. A dynamic alternating direction method of multipliers (ADMM) is proposed to track the varying optimal points of the dynamic ...

The symmetric ADMM with indefinite proximal regularization and its application [PDF]
Journal of Inequalities and Applications, 2017 Due to updating the Lagrangian multiplier twice at each iteration, the symmetric alternating direction method of multipliers (S-ADMM) often performs better than other ADMM-type methods.

DN-ADMM: Distributed Newton ADMM for Multi-agent Optimization [PDF]
2021 60th IEEE Conference on Decision and Control (CDC), 2021 In a multi-agent network, we consider the problem of minimizing an objective function that is expressed as the sum of private convex and smooth functions, and a (possibly) non-differentiable convex regularizer. We propose a novel distributed second-order method based on the framework of Alternating Direction Method of Multipliers (ADMM), by invoking ...
