sure, if you center the data then they are identical. but the uncentered
cosine similarity is quite different, as far as I know.

Yes, that's also the Pearson-correlation-based one, since it forces
the data to be 'centered' (mean of 0) during the computation. In that
case they are actually identical.

Thanks. that makes sense. Which one would be cosine similarity? do you have
that implemented?
