On the effectiveness of persistent homology
Web8 de mar. de 2024 · This article aims to study the topological invariant properties encoded in node graph representational embeddings by utilizing tools available in persistent homology. Specifically, given a node embedding representation algorithm, we consider the case when these embeddings are real-valued. By viewing these embeddings as scalar … WebFigure 22: Persistent homology can be useful in applications where k-dimensional cycles, curvature or convexity are important features. The choice of filtration and persistence signature, including the focus on the long and/or short persistence intervals, depends on the signal of the particular application. - "On the effectiveness of persistent homology"
