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,

Answer by Ingo Mierswa:

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

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.

Cheers,
Ingo

That's great. I look forward to try new features. CVS version is on the sourgeforge.net?

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
