If the network is too selective, the cost function used to generate it
doesn't penalize extreme predictions sufficiently? It was generated using
quadratic cost when it should have been using cross-entropy cost?

Disclaimer: I haven't actually implemented MCTS with NNs, but I have played
around with both techniques.

Would it make sense to artificially scale down the values before the
SoftMax is applied, so the probability distribution is not as concentrated,
and unlikely moves are not penalized as much?

2016-05-22 Thread Rémi Coulom 
Hi,

Thanks for using Crazy Stone.

I tried changes during the week, but nothing worked. So the version that played 
the game was almost identical to the commercial version.

The search did not anticipate Black E8 after B3. It seems the NN makes the 
search too selective. I will investigate more.

Hi, 









It's fun to hear the pro making comments as she goes. I had hoped for a better 
game, though. 
Any comments from the CS camp? 



I'm not from CrazyStone Team but a happy user of CS Deep Learning. 


I analyzed the game (30 000 playouts per move) with the version commercially 
available and it got everything right. I mean every move Hajin Lee questioned 
was also questioned by CrazyStone running on my PC. It includes: 


- questionable attachment in the first joseki they played 
- hane in upper-left corner 
- and finally a blunder at b3 (loosing move) and selection of this joseki as 
well 


Remi said that he's been working hard to improve CS over the last week, but it 
looks like something went wrong and instead he got clearly a weaker program. 
Particularly this B3 is really strange, where right after this white catches 
everything with one move. Remi, what went wrong? 


Cheers, 
Paweł 













Thanks, 
Álvaro.

commercially available and it got everything right. I mean every move Hajin
Lee questioned was also questioned by CrazyStone running on my PC. It
includes:

- questionable attachment in the first joseki they played

[Computer-go] new bot friendly go server.

2016-05-22 Thread Henry Hemming 
Hello, I would like to invite all you go bot developers to my new go server.

http://goratingserver.appspot.com

Here are a few reasons why its bot friendly. Its a simple (and very pretty)
auto match server, with no handicaps, and only such pairings that there is
a reasonable chance for both players to win. The only rule-set is Chinese
and there is no arbitration in scoring, server provides estimate on which
stones are dead, if either player thinks its wrong, they play cleanup,
removing all dead stones from the board. Clock runs even during scoring,
and there is no disconnect protection, ensuring all games finish in a
timely manner. There are no restrictions against bots playing each other,
however pairing algorithm tries to avoid repeat pairings. Accounts rating
are much more accurate than standard elo yet will never get "heavy"
allowing for quick testing of bot features. All games are ranked and there
is no special registration requirements for bots.

While there are hundreds of games being played every day by beta testers
(ranging from double digit kyus to high dans), the server is still in
stealth mode of sorts. I would like to give any bots a few days head start
before opening it to the public. The server provides a RESTful interface,
but there is a simple GTP translation code available for it, which is used
to run Pachi and GnuGo at the moment.
