Accelerated attributed network embedding

X Huang, J Li, X Hu - Proceedings of the 2017 SIAM international conference …, 2017 - SIAM
Network embedding is to learn low-dimensional vector representations for nodes in a
network. It has shown to be effective in a variety of tasks such as node classification and link …

[BOOK][B] MM optimization algorithms

K Lange - 2016 - SIAM
Algorithms have never been more important. As the recipes of computer programs,

Inertial Douglas–Rachford splitting for monotone inclusion problems

RI Boţ, ER Csetnek, C Hendrich - Applied Mathematics and Computation, 2015 - Elsevier
We propose an inertial Douglas–Rachford splitting algorithm for finding the set of zeros of
the sum of two maximally monotone operators in Hilbert spaces and investigate its …

Splitting methods for convex clustering

EC Chi, K Lange - Journal of Computational and Graphical …, 2015 - Taylor & Francis
Clustering is a fundamental problem in many scientific applications. Standard methods such

A two-stage image segmentation method using a convex variant of the Mumford--Shah model and thresholding

X Cai, R Chan, T Zeng - SIAM Journal on Imaging Sciences, 2013 - SIAM
The Mumford--Shah model is one of the most important image segmentation models and
has been studied extensively in the last twenty years. In this paper, we propose a two-stage …

Convex biclustering

EC Chi, GI Allen, RG Baraniuk - Biometrics, 2017 - academic.oup.com
In the biclustering problem, we seek to simultaneously group observations and features.
While biclustering has applications in a wide array of domains, ranging from text mining to …

Weighted variational model for selective image segmentation with application to medical images

C Liu, MKP Ng, T Zeng - Pattern Recognition, 2018 - Elsevier
Selective image segmentation is an important topic in medical imaging and real
applications. In this paper, we propose a weighted variational selective image segmentation …

Clustering using sum-of-norms regularization: With application to particle filter output computation

F Lindsten, H Ohlsson, L Ljung - 2011 IEEE Statistical Signal …, 2011 - ieeexplore.ieee.org
We present a novel clustering method, formulated as a convex optimization problem. The
method is based on over-parameterization and uses a sum-of-norms (SON) regularization to …

Provable convex co-clustering of tensors
