GraphNNK -- Graph Classification and Interpretability
Zeljko Bolevic, Milos Brajovic, Isidora Stankovic +1
Graph Neural Networks (GNNs) have become a standard approach for learning from graph-structured data. However, their reliance on parametric classifiers (most often linear softmax l…
Fourier Analysis of Signals on Directed Acyclic Graphs (DAG) Using Graph Zero-Padding
Ljubisa Stankovic, Milos Dakovic, Ali Bagheri Bardi +2
Directed acyclic graphs (DAGs) are used for modeling causal relationships, dependencies, and flows in various systems. However, spectral analysis becomes impractical in this settin…
Distance and Position Estimation in Visible Light Systems with RGB LEDs
Ilker Demirel, Sinan Gezici
In this manuscript, distance and position estimation problems are investigated for visible light positioning (VLP) systems with red-green-blue (RGB) light emitting diodes (LEDs). T…
Improved Coherence Index-Based Bound in Compressive Sensing
Ljubisa Stankovic, Milos Brajovic, Danilo Mandic +2
Within the Compressive Sensing (CS) paradigm, sparse signals can be reconstructed based on a reduced set of measurements. Reliability of the solution is determined by the uniquenes…
RANSAC-Based Signal Denoising Using Compressive Sensing
Ljubisa Stankovic, Milos Brajovic, Isidora Stankovic +2
In this paper, we present an approach to the reconstruction of signals exhibiting sparsity in a transformation domain, having some heavily disturbed samples. This sparsity-driven s…
Graph Signal Processing -- Part III: Machine Learning on Graphs, from Graph Topology to Applications
Ljubisa Stankovic, Danilo Mandic, Milos Dakovic +4
Many modern data analytics applications on graphs operate on domains where graph topology is not known a priori, and hence its determination becomes part of the problem definition,…
Graph Signal Processing -- Part II: Processing and Analyzing Signals on Graphs
Ljubisa Stankovic, Danilo Mandic, Milos Dakovic +3
The focus of Part I of this monograph has been on both the fundamental properties, graph topologies, and spectral representations of graphs. Part II embarks on these concepts to ad…
On reconstruction algorithms for signals sparse in Hermite and Fourier domains
Milos Brajovic
This thesis consists of original contributions in the area of digital signal processing. The reconstruction of signals sparse (highly concentrated) in various transform domains is…
Graph Signal Processing -- Part I: Graphs, Graph Spectra, and Spectral Clustering
Ljubisa Stankovic, Danilo Mandic, Milos Dakovic +3
The area of Data Analytics on graphs promises a paradigm shift as we approach information processing of classes of data, which are typically acquired on irregular but structured do…
Vertex-Frequency Graph Signal Processing: A review
Ljubisa Stankovic, Danilo P. Mandic, Milos Dakovic +4
Graph signal processing deals with signals which are observed on an irregular graph domain. While many approaches have been developed in classical graph theory to cluster vertices…
Quantization in Compressive Sensing: A Signal Processing Approach
Isidora Stankovic, Milos Brajovic, Milos Dakovic +2
Influence of the finite-length registers and quantization effects on the reconstruction of sparse and approximately sparse signals is analyzed in this paper. For the nonquantized m…
On the Decomposition of Multivariate Nonstationary Multicomponent Signals
Ljubisa Stankovic, Milos Brajovic, Milos Dakovic +1
With their ability to handle an increased amount of information, multivariate and multichannel signals can be used to solve problems normally not solvable with signals obtained fro…
Detection of irregular QRS complexes using Hermite Transform and Support Vector Machine
Zoja Vulaj, Milos Brajovic, Andjela Draganic +1
Computer based recognition and detection of abnormalities in ECG signals is proposed. For this purpose, the Support Vector Machines (SVM) are combined with the advantages of Hermit…
A tool for ECG signal analysis using standard and optimized Hermite transform
Zoja Vulaj, Andjela Draganic, Milos Brajovic +1
The development of a system that would ease the diagnosis of heart diseases would also fasten the work of the cardiologic department in hospitals and facilitate the monitoring of p…
