Report

Autor: Nazari, Mojtaba, Korshøj, Anders Rosendal, Rehman, Naveed ur

A novel method for decomposing a nonstationary signal into amplitude- and frequency-modulated (AM-FM) oscillations and discontinuous (jump) components is proposed. Current nonstationary signal decomposition methods are designed to either obtain const

Multiscale Functional Connectivity: Exploring the brain functional connectivity at different timescales

Autor: Morante, Manuel, Frølich, Kristian, Rehman, Naveed ur

Human brains exhibit highly organized multiscale neurophysiological dynamics. Understanding those dynamic changes and the neuronal networks involved is critical for understanding how the brain functions in health and disease. Functional Magnetic Reso

Time-Varying Graph Mode Decomposition

Autor: Rehman, Naveed ur

Time-varying graph signals are alternative representation of multivariate (or multichannel) signals in which a single time-series is associated with each of the nodes or vertex of a graph. Aided by the graph-theoretic tools, time-varying graph models

Data-driven Signal Decomposition Approaches: A Comparative Analysis

Autor: Eriksen, Thomas, Rehman, Naveed ur

Signal decomposition (SD) approaches aim to decompose non-stationary signals into their constituent amplitude- and frequency-modulated components. This represents an important preprocessing step in many practical signal processing pipelines, providin
