So yes there is a difference between the two depending on the size of the
matrix.
Following is an output from ipython:

I have no idea about the comparison with
sklearn.decomposition.IncrementalPCA.
Was not aware of this but from the code it seems to be a different approach.
I will try to come with some numbers.

The update part is handy when you are doing live observations for
instance and you want a quick way to update your PCA without having to
recompute the whole thing
Hi,
how does it compare with:

Hi everyone,
I have some code that allows to upgrade (or downgrade) a PCA with a new
sample.
The update part is handy when you are doing live observations for instance
and you want a quick way to update your PCA without having to recompute the
whole thing from scratch.
Are you interested in this?
