Computing multiparameter persistent homology through a discrete Morse-based approach [article]

Sara Scaramuccia and Federico Iuricich and Leila De Floriani and Claudia Landi
2018 arXiv   pre-print
We propose a new algorithm, well suited for parallel and distributed implementations and we provide the first evaluation of the impact on MPH computations of a preprocessing approach.  ...  In this paper, we consider discrete Morse Theory as a tool to simplify the computation of MPH on a multiparameter dataset.  ...  The basic goal of Topological Data Analysis (TDA) is to retrieve and organize qualitative information about data.  ...

Computational and Theoretical Issues of Multiparameter Persistent Homology for Data Analysis [article]

SARA SCARAMUCCIA
2018
In this context, homology is one of the most relevant topological descriptors, well-appreciated for its discrete nature, computability and dimension independence.  ...  Multipersistent homology presents several issues in terms of feasibility of computations over real-sized data and theoretical challenges in the evaluation of possible descriptors.  ...  Challenging tasks in Visualization comprise the integration of both scientific and information visualization, and the detection of relevant features [116] .  ...
