The Alternating Direction Method of Multipliers An ADMM Software Library

چکیده

The Alternating Direction Method of Multipliers (ADMM) is a method that solves convex optimization problems of the form min(f(x) + g(z)) subject to Ax + Bz = c, where A and B are suitable matrices and c is a vector, for optimal points (xopt, zopt). It is commonly used for distributed convex minimization on large scale data-sets. However, it can be technically difficult to implement and there is no known way to automatically choose an optimal step size for ADMM. Our goal in this project is to simplify the use of ADMM by making a robust, easy-to-use software library for all ADMM-related needs, with the ability to adaptively select step-sizes on every iteration. The library will contain a general ADMM method, as well as solvers for common problems that ADMM is used for. It also tries to implement adaptive step-size selection, have support for parallel computing and have user-friendly options and features.

Modified Convex Data Clustering Algorithm Based on Alternating Direction Method of Multipliers

Knowing the fact that the main weakness of the most standard methods including k-means and hierarchical data clustering is their sensitivity to initialization and trapping to local minima, this paper proposes a modification of convex data clustering  in which there is no need to  be peculiar about how to select initial values. Due to properly converting the task of optimization to an equivalent...

Bregman Alternating Direction Method of Multipliers

The mirror descent algorithm (MDA) generalizes gradient descent by using a Bregman divergence to replace squared Euclidean distance. In this paper, we similarly generalize the alternating direction method of multipliers (ADMM) to Bregman ADMM (BADMM), which allows the choice of different Bregman divergences to exploit the structure of problems. BADMM provides a unified framework for ADMM and it...

Investigating Image Inpainting via the Alternating DirectionMethod of Multipliers

In many imaging applications, there exists potential for corruption of the images by sources of structured noise that completely loses original pixel information. The reconstruction of the original image from its corrupted observation is known as image inpainting. This paper seeks to investigate image inpainting using a particular algorithm, the alternating direction method of multipliers (ADMM...

Separable Model Predictive Control via Alternating Direction Method of Multipliers for Large-scale Systems

In this paper, an alternating direction method of multipliers (ADMM) based realtime model predictive control (MPC) algorithm is presented. With the use of indicator function and by introducing extra consensus constraints, the constrained MPC problem can be formulated as a separable MPC problem, which can be computed very efficiently by projected gradient descent ADMM update steps and Riccati re...
