Hi Michael and Kyle,
thanks to you both for the fast replies!
(and Kyle, nice to see you here too!)
To give this a bit of context, I implemented Barber’s algorithm in Julia and
used the scikit-learn implementation to check my results (and also to get hints
for fixing numerical instability iss
I haven't looked closely, but is Barber's data format considered to be
examples as columns, or examples as rows? That difference is usually what I
see in a bunch of different SVD based algorithms. It is very annoying when
reading the literature.

I am not sure if this is the exact issue here, but note that data in
sklearn is represented row-wise: One data point per row. This means that
the feature names are indicated by the columns.
Now, after SVD, U is a matrix that lives in sample space and VT is a matrix
that lives in feature space. The
