Vertex-frequency analysis (VFA) is a useful technique in graph signal processing to extract the correspondence between frequencies and vertices. VFA can be calculated by the windowed graph Fourier ...

Firstly, in the graph representation and preprocessing stage, the input graph is subjected to symmetric normalization and feature normalization preprocessing to obtain a normalized adjacency matrix ...

Simple graphs are undirected, while more powerful graphs include causal relationships to allow causal inference. Figure 1. A simple example of a knowledge graph. (QIAGEN Digital Insights) ...

3. Hyperdimensional Graph Representation In this section, we explain how to represent graph structure in high-dimensional space. We exploit hyperdimensional mathematics, introduced in Section 2.1, to ...

Multi-Relational Graph In addition to the distinction between undirected, directed, and weighted edges we will look at graphs with different types of edges. For example in the graph depicting ...
