Hi Martin - Would you be willing to share some of the sgf game records played by your > network with the community? I tried to replay the game record in your > paper, but got stuck since it does not show any of the moves that got > captured.
Sorry about that, we will correct the figure and repost. In the meanwhile Aja will post the .sgf for that game. Also, thanks for noticing that we tested against a stronger version of Fuego than Clark and Storkey, we'll evaluate against Fuego 1.1 and post the results. Unfortunately, we only have approval to release the material in the paper, so we can't really give any further data :-( One more thing, Aja said he was tired when he measured his own performance on KGS predictions (working too hard on this paper!) So it would be great to get better statistics on how humans really do at predicting the next move. Does anyone want to measure their own performance, say on 200 randomly chosen positions from the KGS data? - Do you know how large is the effect from using the extra features that > are not in the paper by Clarke and Storkey, i.e. the last move info and the > extra tactics?

We trained our networks before we knew about Clark and Storkey's results, so we haven't had a chance to evaluate the differences between the approaches. But it's well known that last move info makes a big difference to predictive performance, so I'd guess they would already be close to 50% predictive accuracy if they included those features. > - Is there a way to simplify the final network so that it is faster to > compute and/or easier to understand?

This is an interesting idea, but so far we only focused on building a large and deep enough network to represent Go knowledge at all. Cheers Dave
