title: 'manifoldsculpting: Nonlinear Dimensionality Reduction by Manifold Sculpting'
version: 1.2.1
doi: 10.32614/CRAN.package.manifoldsculpting
abstract: Manifold Sculpting (Gashler, Ventura and Martinez (2008) <https://proceedings.neurips.cc/paper/2007/hash/c06d06da9666a219db15cf575aff2824-Abstract.html>)
  is an iterative nonlinear dimensionality reduction method. It records the distances
  and angles between each point and its nearest neighbors, then gradually scales the
  data out of the dimensions to be removed while moving the points in the remaining
  dimensions to restore these local relationships, as if surface tension were acting
  on the manifold. New samples are embedded by solving the same local problem against
  the training embedding. The neighbor search and the sculpting iterations are written
  in C++ with 'RcppArmadillo', and step_manifold_sculpting() makes the method available
  as a 'recipes' preprocessing step for 'tidymodels' workflows.
