Eigenvalues of Symmetric Non-normalized Discrete Trigonometric Transforms
Ali Bagheri Bardi, Milos Dakovic, Taher Yazdanpanah +1
A comprehensive approach to the spectrum characterization (derivation of eigenvalues and the corresponding multiplicities) for non-normalized, symmetric discrete trigonometric tran…
Unitary Shift Operators on a Graph
Bruno Scalzo Dees, Ljubisa Stankovic, Milos Dakovic +2
A unitary shift operator (GSO) for signals on a graph is introduced, which exhibits the desired property of energy preservation over both backward and forward graph shifts. For rig…
A Class of Doubly Stochastic Shift Operators for Random Graph Signals and their Boundedness
Bruno Scalzo Dees, Ljubisa Stankovic, Milos Dakovic +2
A class of doubly stochastic graph shift operators (GSO) is proposed, which is shown to exhibit: (i) lower and upper -boundedness for locally stationary random graph signals…
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…
An Example-Driven Introduction to Data Analytics on Graphs
Ljubisa Stankovic, Danilo Mandic, Milos Dakovic +3
Graphs are irregular structures which naturally account for data integrity, however, traditional approaches have been established outside Signal Processing, and largely focus on an…
