Plex is a Java package developed
as a research tool for building and studying persistent homology of
simplical complexes, generated from real or synthetic
point-cloud data.
For an older, C++ based version of Plex, check here. This version of PLEX is more capable than the newer version in some respects, such as cohomology calculations etc.
A computational method for extracting simple descriptions of high dimensional data sets in the form of simplicial complexes. Mapper is based on the idea of partial clustering of the data guided by a set of functions defined on the data. Mapper is not dependent on any particular clustering algorithm, i.e. any clustering algorithm may be used with Mapper.
