NeighborhoodPreservingEmbedding converter used to construct embeddings as described in:
He, X., Cai, D., Yan, S., & Zhang, H.-J. (2005). Neighborhood preserving embedding. Tenth IEEE International Conference on Computer Vision ICCV05 Volume 1, 2, 1208-1213. Ieee. Retrieved from http://ieeexplore.ieee.org/lpdocs/epic03/wrapper.htm?arnumber=1544858
This method is hardly applicable to very high-dimensional data due to necessity to solve eigenproblem involving matrix of size (dim x dim).
