Dynamic Graph Learning: A Structure-Driven Approach
MATHEMATICS, 9(2).
author keywords: dynamic graph learning; graph signal processing; sparse signal; convex optimization
TL;DR:
The purpose of this paper is to infer a dynamic graph as a global model of time-varying measurements at a set of network nodes, which captures both pairwise as well as higher order interactions among the nodes.

Community Detection and Improved Detectability in Multiplex Networks
IEEE TRANSACTIONS ON NETWORK SCIENCE AND ENGINEERING, 7(3), 1697–1709.
author keywords: Multiplexing; Stochastic processes; Belief propagation; Correlation; Periodic structures; Computational modeling; Bayes methods; Network theory (graphs); graphical models; belief propagation
TL;DR:
A generative model that leverages the multiplicity of a single community in multiple layers, with no prior assumption on the relation of communities among different layers is proposed, which shows a better detection performance over a certain correlation and signal to noise ratio (SNR) range.

Deep Dictionary Learning: A PARametric NETwork Approach
IEEE TRANSACTIONS ON IMAGE PROCESSING, 28(10), 4790–4802.
author keywords: Image classification; deep learning; sparse representation
TL;DR:
The performance of the proposed hierarchical method increases by adding more layers, which consequently makes this model easier to tune and adapt and shows a remarkably lower fooling rate in the presence of adversarial perturbation.

Sparse Generative Adversarial Network
2019 IEEE/CVF INTERNATIONAL CONFERENCE ON COMPUTER VISION WORKSHOPS (ICCVW), pp. 3063–3071.
TL;DR:
A new approach to Generative Adversarial Networks (GANs) to achieve an improved performance with additional robustness to its so-called and well-recognized mode collapse, by mapping the desired data onto a frame-based space for a sparse representation to lift any limitation of small support features prior to learning the structure.

Robust Subspace Clustering by Bi-sparsity Pursuit: Guarantees and Sequential Algorithm
2018 IEEE WINTER CONFERENCE ON APPLICATIONS OF COMPUTER VISION (WACV 2018), pp. 1302–1311.
TL;DR:
This work considers subspace clustering under sparse noise, and provides an analysis of this optimization problem demonstrating that this approach is capable of recovering linear subspaces as a local optimal solution for sufficiently large data sets and sparse noise vectors.

Performance Analysis of Sparsity-Based Parameter Estimation
IEEE TRANSACTIONS ON SIGNAL PROCESSING, 65(24), 6478–6488.
author keywords: Superresolution theory; performance bounds; error analysis; LASSO; atomic norm regularization; atomic decomposition; continuous LASSO; off-grid estimation
TL;DR:
A novel analysis of the LASSO as an estimator of continuous parameters by providing a novel framework for the analysis by studying nearly ideal sparse solutions and quantifying the error in the high signal-to-noise ratio regime.
