- StephenAshmore 11y agoSure. These techniques are called Dimensionality Reduction or manifold learning. The wikipedia article actually has a good description: https://en.wikipedia.org/wiki/Nonlinear_dimensionality_reduction https://en.wikipedia.org/wiki/Nonlinear_dimensionality_reduc... Some of the more interesting ones: locally linear embedding, isomap, MLLE, Maximum Variance Unfolding.
- micwawa 11y agoI think one of the seminal papers is by Belkin and Niyogi: http://people.cs.uchicago.edu/~niyogi/papersps/BNcolt05.pdf http://people.cs.uchicago.edu/~niyogi/papersps/BNcolt05.pdf
