[Scikit-learn-general] Out of sample extensions

[David Collins]

Are the any out of sample extensions available for the LLE and ISOMAP
reduction methods? If not, can they simply be implemented with existing
scikit/numpy methods?

There actually seems to be a pretty well-cited Bengio 2003 NIPS paper:
http://papers.nips.cc/paper/2461-out-of-sample-extensions-for-lle-isomap-mds-eigenmaps-and-spectral-clustering.pdf

Maybe we should implement that?
