###SMMC A programm written during a Mathematical Contest in Modeling in late 2015. SMMC is a manifold clustering method solving the hybrid nonlinear manifold clustering problem, which is able to handle situations where the manifolds on which the data points lie are (a) linear and/or nonlinear and (b) intersecting and/or not intersecting. It first applies MPPCA (Mixtures of Probabilistic Principal Component Analyzers) to break the intersection regions into a collection of good local patches according to the underlying clusters/maniflods which is an important step to separate multiple manifolds with intersections, then uses spectral clustering with a suitable constructed affinity matrix to find the clusters.

It's nice.
