Comment (by birm):

 So, the results don't seem exactly promising.
 I've attached "Results_mnist" to the ticket.
 New dimension is set to 711, because at dimension 712 it fails, or at
 least takes more than twelve hours.

 Equally concerning is the fact that it fails an overwhelming majority of
 the time, even when the test tolerance is 100x the convergence tolerance.
 Also, it's slower now.

 It did work quite well to okay for certain datasets; this one seems quite
 bad though.
