There was a problem hiding this comment.
@Intron7 you said it would be possible to adapt the code to do TruncatedSVD as well?
I think this PR is pretty clean, so maybe we can extend it in another PR?

Agree, PR into this PR if we start pre-merge

Sorry, something went wrong.

Can we add a test here to find out (or to at least know) how far our implementation here is from #3296 for sparse? |

Done! |

An alternative would be to subclass
PCA, but that would involve erroring out or reimplementing all of its options.Ideally #3267 would be merged first and this one integrated into its improved decision tree.
