For the moment, there are 3 additional libraries :
- one for my dimensionality reduction technique (that could be rewritten in
- one for a neighborhood search (that could rely on ANN ?), used in one of
the regression function
- one for solving the correlation clustering problem
The last one is not feasible in Python, too slow, and even this
implementation needs tweaking to use a memory-aware clustering approach.
I didn't implement every flavour of Isomap, but those can be easily added,
after a first version is released.
Once this part of the machine learning scikit is no longer a TP and if David
gives his approval, I will build eggs so that everyone can use it.
Thanks for the feedback ;)
