msr-package: Data Analysis with the Morse-Smale Complex


Discrete Morse-Smale complex approximation based on k-NN graph. The Morse-Smale complex provides a decomposition of the domain. This package provides methods to compute a hierarchical sequence of Morse-Smale complicies and tools that exploit this domain decomposition for regression and visualization of scalar functions.



The core functionality rests on the discrete approximation of the Morse-Smale complex from a sample of a function (see msc.nn, msc.nn.svm, msc.nn.kd.

Based on this functionality the regression approach in [2] (see msc.lm and msc.slm) and the explorartory data anlsysis approach based on the visualization in [3] (see plot.msc) is implemented.
