Topological data analysis


The area of Topological Data Analysis (TDA) has emerged recently as being that part of Computational Topology concerned with applying the methods of that subject to the analysis of data sets that are often of very large size; the methods used are adapted from algebraic topology and differential topology and are closely related to those used for spatial reconstruction from scanned data in Visualisation, but the context is, theoretically, not limited to low dimensions nor to data of spatial origin nor, initially, to the visualisation of the data. Its aim, rather, is to give qualitative information on the data, allowing for statistical variation, noise etc.

Cohomotopy in topological data analysis

The suggestion to regard cobordism theory of iso-hypersurfaces, and thus Pontryagin's theorem in Cohomotopy, as a tool in (persistent) topological data analysis (improving on homologuical well groups):
