Fast construction of the Vietoris-Rips complex

چکیده

The Vietoris-Rips complex characterizes the topology of a point set. This complex is popular in topological data analysis as its construction extends easily to higher dimensions. We formulate a two-phase approach for its construction that separates geometry from topology. We survey methods for the first phase, give three algorithms for the second phase, implement all algorithms, and present experimental results. Our software can also be used for constructing any clique complex, such as the weak witness complex.

Vietoris-Rips and Cech Complexes of Metric Gluings

We study Vietoris–Rips and Čech complexes of metric wedge sums and metric gluings. We show that the Vietoris–Rips (resp. Čech) complex of a wedge sum, equipped with a natural metric, is homotopy equivalent to the wedge sum of the Vietoris–Rips (resp. Čech) complexes. We also provide generalizations for certain metric gluings, i.e. when two metric spaces are glued together along a common isometr...

The Vietoris-Rips complexes of a circle

Given a metric space X and a distance threshold r > 0, the Vietoris–Rips simplicial complex has as its simplices the finite subsets of X of diameter less than r. A theorem of JeanClaude Hausmann states that if X is a Riemannian manifold and r is sufficiently small, then the Vietoris–Rips complex is homotopy equivalent to the original manifold. Little is known about the behavior of Vietoris–Rips...

Vietoris-Rips Complexes of Planar Point Sets

Fix a finite set of points in Euclidean n-space En, thought of as a point-cloud sampling of a certain domain D ⊂ En. The VietorisRips complex is a combinatorial simplicial complex based on proximity of neighbors that serves as an easily-computed but high-dimensional approximation to the homotopy type of D. There is a natural “shadow” projection map from the Vietoris-Rips complex to En that has ...

Statement of Current Research

I am interested in computational topology and geometry, combinatorial topology, and topology applied to data analysis and to sensor networks. My current research: §1. Advances the theory of Vietoris–Rips simplicial complexes. Given a set of points X sampled from a metric space M , what information can one recover about M? One approach is to build a Vietoris–Rips simplicial complex, which depend...
