Researchers have introduced Topological Signal Processing (TSP) as a generalization of Graph Signal Processing (GSP) to analyze complex datasets. TSP extends signal analysis beyond nodes to edges and higher-dimensional elements within simplicial complexes, enabling the study of higher-order interactions. The paper provides an accessible tutorial on TSP foundations, focusing on techniques using the combinatorial Hodge Laplacian and demonstrating its application in analyzing brain imaging data to reveal complex interactions between brain regions.
