revanalyzer.vectorizers.landscape_vectorizer
Definition of Landscape vectorizer, used in PD vectorization. A persistence landscape is a collection of 1D piecewise-linear functions computed from the rank function associated to the persistence diagram. These piecewise-linear functions are then sampled evenly on a given range and the corresponding vectors of samples are concatenated and returned. See Bubenik, P. (2015). Statistical topological data analysis using persistence landscapes. J. Mach. Learn. Res., 16(1), 77-102.
