Persistent homology of complex networks
WebPH-STAT is introduced, a comprehensive Matlab toolbox designed for performing a wide range of statistical inferences on persistent homology and aims to provide users with an accessible and user-friendly interface for analyzing and interpreting topological data. We introduce PH-STAT, a comprehensive Matlab toolbox designed for performing a wide … WebPersistent homology is visualized through a barcode or persistence diagram. The barcode has its root in abstract mathematics. Namely, the category of finite filtered complexes over a field is semi-simple. Any filtered complex is isomorphic to its canonical form, a direct sum of one- and two-dimensional simple filtered complexes. Stability [ edit]

WebComplex Networks Definition: A network is a complex system consisting of individuals or entities connected by specific ties such as Personal Relationship Shared Knowledge … Web1. nov 2024 · We present the application of topological data analysis (TDA) to study unweighted complex networks via their persistent homology. By endowing appropriate weights that capture the inherent topological characteristics of such a network, we convert an unweighted network into a weighted one.
Web26. dec 2024 · We study the persistent homology of a data set of syntactic parameters of world languages. We show that, while homology generators behave erratically over the whole data set, non-trivial persistent homology appears when one restricts to specific language families. Different families exhibit different persistent homology. WebWe first give a formal definition to network and ego network of a vertex in the network, then define simplicial complexes and persistent homology. We also provide related work in this section. In Section 3, we introduce the proposed bot detection model by explaining our weighted ego network representation and topological feature extraction method.
