Can anyone give me a pointer on what techniques the author is talking about for unsupervised learning at the end of the article?



Sure. These techniques are called Dimensionality Reduction or manifold learning. The wikipedia article actually has a good description: https://en.wikipedia.org/wiki/Nonlinear_dimensionality_reduc... Some of the more interesting ones: locally linear embedding, isomap, MLLE, Maximum Variance Unfolding.


I think one of the seminal papers is by Belkin and Niyogi:
