Re: Python version of CGOS by Zakki

Another remark: do you plot the win rate of the most visited move? Instead of plotting the win_rate and score of a single move, it would seem better to provide the win_rate and score (and visit count) at the root.

Re: Python version of CGOS by Zakki

Hi, So I made a first try today. This is the game it produced: http://203.138.189.63/cgos/viewer.cgi?19x19/SGF/2023/01/26/425.sgf It is a bit strange, because in order to produce a plot, I have to go to the end of the game, and undo moves one by one. Otherwise, nothing is displayed. I started the ga...

Re: Python version of CGOS by Zakki

Great job! Strangely, I could not see any data from the sgf you linked. But I could on this one: http://203.138.189.63/cgos/viewer.cgi?19x19/SGF/2023/01/24/207.sgf It is difficult to guess the meaning of the plot. Which color is which player? I am a bit busy now, but I plan to implement the gtp exte...

Re: Python version of CGOS by Zakki

Hi,

Great to have you here. Welcome to the forum!

It is really great to be able to visualize evaluation plots from CGOS. What are the specs of those gtp extensions so that I can implement it in my program?

Re: beating KataGo by Adversarial attack

Thanks, these are interesting results. I have always felt that it is a fundamental weakness of the AlphaZero approach that the training set is made of self-play games: it does not learn to handle positions that do not occur between very strong players. That may be why Leela Zero had a lot of trouble...
