Hi Denis.
As far as I know there was no change in MiniBatchKMeans.
Was the result you had before robust?I would guess
that there is something non-deterministic somewhere.
MiniBatchKMeans uses a random initialisation and can easily fall into
local minimas. If you want to compare the 0.11 version against the
0.12 version, you need to use the same initialisation (possible by
fixing the seed).
Right, the initialization. Thanks Nelle, I didn't have a coffee yet ;)
