A reference for scaled PCA initialisation

[dkobak]

Hey, do you by any chance know of any reference for the scaled PCA initialization? Perhaps there is some paper that at least mentions PCA initialization as a possibility and explicitly says that one needs to use scaled PCA in this case? I am not able to find any reference at all.

I looked here https://jlmelville.github.io/smallvis/init.html and here http://jlmelville.github.io/sneer/references.html but did not find anything. In fact, in your References list you cite our preprint in the Initialization setting, but I think I borrowed the scaled PCA idea from your pages :-) I am preparing a revision right now and it'd be good to have some reference for this...

I think I came up with the scaled PCA idea on my own. The JSE paper uses PCA as initialization so that was the direct inspiration, although any requirement for scaling isn't mentioned.

Thanks. I guess I will add a citation directly to https://jlmelville.github.io/smallvis/init.html then.

(This is what I did in the end, so I'm closing it ;-)
