In the light of my recent discovery of the statistics module in imp, I
was wondering if some of you would be interested in an implementation of
self-organizing maps (SOM). They are a generalization of principal
components analysis to nonlinear models.
There's a shortcut for us to have it in IMP. It's called GPLVM, and is a
probabilistic SOM based on gaussian processes. Is that something that
would interest anyone?
Sure, but the paper describes how it is made. I already wrote an
implementation of the gaussian process, and one would just need to adapt
it to this case by writing the covariance function and its derivatives.
I'm willing to do it, although I'd really appreciate some programming
help to speedup things, but I wasn't going to do it without anyone
interested. As far as where to put it, the core of the gaussian process
is in the isd module, so no need to rename stuff for the moment.
