MultiViewICA

[hugorichard]

I have developped recently a new method called MultiViewICA.
https://proceedings.neurips.cc/paper/2020/file/de03beffeed9da5f3639a621bcab5dd4-Paper.pdf
It does the same thing as SRM but yields significantly better results.
I currently have a standalone implementation of it here:
https://github.com/hugorichard/multiviewica
In practice, I use SRM to reduce the data and MultiViewICA is applied on the reduced data.
I believe it would be nice to have it directly in Brainiak so that users can use it more easily.
If you think this is a good idea, I'll make a pull request.

Hello, @hugorichard! I think that's a great idea. Aside from python-picard, which looks fine, I see no new dependencies.

Let's hear also from our SRM team. @TuKo, @qihongl?

Actually I would like to make https://github.com/hugorichard/multiviewica
a dependency as other people are already relying on this code. Would that be fine with you ?

In that case, what would the BrainIAK contribution be?

This integration of SRM and MultiViewICA

[hugorichard]

so that people can just do MultiViewICA.fit() and it performs first SRM and then MultiViewICA on reduced data.

I see. It seems to me less compelling than incorporating MultiViewICA, but let's hear from others as well...

Hi @hugorichard. Thanks for thinking of contributing to BrainIAK! Since the major code is not going to come into BrainIAK, how do you think about making a new example notebook in funcalign folder that shows how to use SRM and MultiViewICA together?

[hugorichard]

Hi @lcnature ! I think that is a great idea. If you think that's interesting, I'll work on that.

Yes, an example would be great!
