It may depend on what you mean by "ftp site". The positions at 
ftp://ftp.demon.nl/pub/Museum/Demon/games/gnubg/nn-training/training_data/ 
or http://files.gnubg.com/media/nn-training/nl20040621/training_data/ are 
from Joseph Heled. The output values are probably 2ply evaluations by the 
previous iteration of the nets.

At http://files.gnubg.com/media/nn-training/pmichel/training_data/ ,about 
49% of the training positions are the same as above, from Joseph Heled's 
work in the mid-2000s, 49% more are the same positions with the other 
player on roll and the last 1-2% are those I added. The output values are 
rollouts.

I don't "feel ownership" of anything there.

I'm not sure how the could get something out of that in the current 
format, with the key for each row being an obscure string. Would 
converting this to a suitable format mean to something looking more like a 
backgammon board ?
