Hello all,

Are there any plans to include Nonlinear Dimensionality Reduction techniques like ISOMAP and LLE in RM?

Regards,
Vijay


Answer by Jean-Charles:

Hi Vijay,

I do not know the techniques you quoted. Are they related to kernel-based PCA ?
Cheers,
Jean-Charles.


Answer by Ingo Mierswa:

At least we already plan a Kernel-PCA for the next release.

Cheers,
Ingo

    Hello Vijay,

    thanks for pointing this out. We will have a look into this and see if we can incorporate these techniques. By the way: the latest CVS version (and also the next release) already contain a Kernel-PCA.

    Hi All,

    After "kernel-PCA", here is "kernel-ICA". Would it be implemented for RM 5.0 ?

    This is actually already on our todo list. So let's see if we manage to add it until 5.0  ;)
