  1. [Thrun] In modern dimensionality reduction, the trick has been to define nonlinear,
  2. sometimes piece-wise linear, subspaces on which data is being projected.
  3. This is not dissimilar from K nearest neighbors,
  4. where local regions are being defined based on local data neighborhoods.
  5. But here we need ways to interpret leveraging neighbors
  6. to make sure that the subspace itself becomes a feasible subspace.
  7. Common methods include local linear embedding, or LLE, or the Isomap method.
  8. If you're interested in this, check the Web.
  9. There's tons of information on these methods on the World Wide Web.
