The Interconnectivity Vector: A Finite-Dimensional Vector Representation of Persistent Homology

no code implementations23 Nov 2020 Megan Johnson, Jae-Hun Jung

In this paper we propose a new finite-dimensional vector, called the interconnectivity vector, representation of a PD adapted from Bag-of-Words (BoW).
