This concerns both the analysis of network structure as well as its dynamics. The supporting examples demonstrate the promise of In particular, targeting dynamic, temporal, and continuous sequential data, Graph Signal Processing (GSP) 24 has emerged as a prominent and versatile framework for analyzing such complex data. Representation (eigenanalysis) which illustrates the power of graphs in variousĭata association tasks. Finally, a framework for vertexĬlustering and graph segmentation is established based on graph spectral Next, to illustrate estimation strategies performed on graph signals, spectralĪnalysis of graphs is introduced through eigenanalysis of mathematicalĭescriptors of graphs and in a generic way. Higher-order graph properties, such as cuts, walks, paths, and neighborhoods. Shown to convey physical meaning related to both graph topology and

The eigenvalues and eigenvectors of graph Laplacian and adjacency matrices are This serves as a basis for spectral analysis of graphs, whereby Through a linear algebraic formalism of graph topology (vertices, connections,ĭirectivity). To fill this void, we first revisit graph topologies from aĭata Analytics point of view, and establish a taxonomy of graph networks Probabilistic inference, clustering and separation from signals and dataĪcquired on graphs. Learning strategies, such as detection, estimation, statistical and The optimization of graphs themselves, rather than on directly inferring Yet, despite its long history, current approaches mostly focus on Irregular but structured domains (social networks, various ad-hoc sensor Information processing of classes of data, which are typically acquired on

Vertex domain windows and the inversion conditions and relations.

Important topics related to the local graph Fourier transform (LGFT) areĬovered, together with its various forms including the graph spectral and Referred to as the vertex-frequency analysis, since it can be considered as anĮxtension of classical time-frequency analysis to the graph domain of a signal. Localized graph signal analysis in the joint vertex-spectral domain is Sampling of graph signals are presented and further linked with compressive

Including Chebyshev polynomial approximation series. The spectral domain representations are then used as theīasis to introduce graph signal filtering concepts and address their design, Representation of graph signals and systems is the Graph Discrete Fourier Graph signal shift operators, which generalize the corresponding principlesįrom traditional learning systems. The concept of systems on graph is defined using Intuitive, yet illustrative and general enough case study of multisensor Theįundamental ideas related to graph signals are introduced through a simple and Part IIĮmbarks on these concepts to address the algorithmic and practical issuesĬentered round data/signal processing on graphs, that is, the focus is on theĪnalysis and estimation of both deterministic and random data on graphs.
