Fuzzy Neighbourhood Preserving Analysis with QR-Decomposition

Feature reduction (projection) using fuzzy discriminant analysis with QR-decomposition.

Refer to the following papers for a description. Also note that you can play around with the parameters to optimize the performance, if it is not good enough on your dataset, thought it should be.
