Hi, I'd like to improve ICA as discussed in #2113. Also I'd like to inquire memory behavior of the decomposition classes to better support their combined application on bog data sets with more than 100k samples. Also I'd like to take a look at API inconsistencies between those classes, e.g with

What is everyone planning to work on? Just curious :) I'd like to implement the kernelCCA, but before doing that, I might have to refactor the PLS module, which is starting to be a bit crowded. I also plan on fixing some of the issues of the MDS (use an SVD when possible). Will you be joining

Hi Mathieu, Will you be joining online? People have been asking this on IRC ;) Personally I want to take care of unfinished business like the omp CV, the RBM pull request, GSOC PRs, and I was thinking of trying to tackle Averaged SGD; apart from this I'll be side-sprinting on pystruct. Cheers,
