DimensionReduction
DimensionReduction[{example1,example2,…}] generates a DimensionReducerFunction[…] that projects from the space defined by the examplei to a lower-dimensional approximating manifold.
DimensionReduction[examples,n] generates a DimensionReducerFunction[…] for an n-dimensional approximating manifold.
DimensionReduction[examples,n,props] generates the specified properties of the dimensionality reduction.
