class HessianLocallyLinearEmbedding used to preprocess data using Hessian Locally Linear Embedding algorithm as described in
Donoho, D., & Grimes, C. (2003). Hessian eigenmaps: new tools for nonlinear dimensionality reduction. Proceedings of National Academy of Science (Vol. 100, pp. 5591-5596).
Be sure k value is set with at least 1+[target dim]+1/2 [target_dim]*[1 + target dim], e.g. greater than 6 for target dimensionality of 2.
Uses implementation from the Tapkee library.
To use this converter with static interfaces please refer it by sg('create_converter','hlle',k);

Builds a dictionary of all parameters in SGObject as well of those of SGObjects that are parameters of this object. Dictionary maps parameters to the objects that own them.

Creates a clone of the current object. This is done via recursively traversing all parameters, which corresponds to a deep copy. Calling equals on the cloned object always returns true although none of the memory of both objects overlaps.

Recursively compares the current SGObject to another one. Compares all registered numerical parameters, recursion upon complex (SGObject) parameters. Does not compare pointers!
May be overwritten but please do with care! Should not be necessary in most cases.
