I think one of the main problems is that the network learns good replies
to good moves. The training set does not have good replies to bad moves,
but the search tree is full of bad moves that need to be punished.
Alvaro's suggestion looks good. This is one of the experiments I want to
try.

If the network is too selective, the cost function used to generate it

using quadratic cost when it should have been using cross-entropy cost?

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?

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.

Objet: Re: [Computer-go] Hajin Lee will play a live commented
game against CrazyStone
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.

Hi,
I am very happy to announce that Hajin Lee will play a live
commented game against Crazy Stone on Sunday, at 8PM Korean
time. The game will take place on KGS, and she will make live
comments on her youtube channel.
