Yeah there is something really wrong with the face recognition, it is simply
not working as it should - not exactly a hard thing to do any more either, the
tech has been out for a very long time.  So not only are we met with 4 days or
more of waiting to detect faces, then we're met with bad results.  It's quicker
to do them manually, even for 90,000 images and that's embarrassing.

I suspect, clicking minus (not this person) and tick (yes this person), is not
actually training the model as it should be.  That's what it 'feels' like to
me, but could be wrong.  This is still happening on 8.3.0.

I have access to Windows, Linux and Mac and various drives and an Nvidia GPU if
anyone wants me to help in any way.

On my wish list, we would get GPU acceleration working first, which seems
counter intuitive if it gives bad results, but the reasoning is we don't have
to wait days and redo it all the time just to find out it didn't work.

Then after GPU we would focus on quality face matching problems.  Unless of
course it's a simple as 'oh the tick and minus aren't actually training it',
then yeah, probably pays to do that.

I also have a large number of scanned negatives that are 300MB tiffs at
4800dpi.  Obviously they're slow.  The faces do detect though.  But perhaps
that screws up the recognition system, I don't know.

Sadly, in my relatively new, but fairly exhausting usage (exhausting as in time
spent this weekend), face detection really isn't a working feature.  Hopefully
we can get it fixed.
