Re: Opening book read speed

Ok, if you do move generation and all that stuff once per move string when reading the book into memory then it is quite reasonable. But I would not do that at all with a book in line-oriented text format. Instead I would only build a tree of move strings in memory, that should be pretty fast, also ...

Re: Opening read speed

Of course, good question ... because my book is not in the "position hash -> list of good moves" format but in a "line" format... Even then it should not take 10 seconds to read and parse the book. Reading it takes milliseconds, and parsing text would not qualify to take that long, either, for me. ...

Re: Something goes wrong with lc0 since yesterday?

One won game by Lc0 which it managed to draw in what seems to be even a bug: [...] 6r1/2PK4/3B2p1/8/6k1/8/8/R7 w - - 8 76 White Lc0 ID10610 to move. Draw! Agreed, this must be a bug, why doesn't LC0 promote the pawn? Another, a completely drawn late endgame, which Lc0 manages to lose, playing reall...

Makes same number of mistakes as white does. Might be another bug or not enough network tuning.
Let's be honest: you won't make a bet that there are less than five other bugs left in it, will you? :D

Maybe he is a "training data provider"?
How about 'trainer' or 'coach'?
I think the "trainer" in this case is a program.

Re: Copyright and Machine Learning IP

What this program does is not like compilation of source code, and the NN weights are not another representation of source code resulting from some transformation. This is debatable. The weights are another representation of a (part of) the knowledge contained in the training data set. How to obtai...

Re: Copyright and Machine Learning IP

And there is no good reason at all to credit AS [...] Maybe he is a "training data provider"? For me his contribution is, at least remotely, comparable to that of an opening book creator who uses an existing book creation tool and feeds selected games into it. Or, perhaps even more closely related ...

Re: Copyright and Machine Learning IP

NN weights are intellectual property, but they are not source code. The GPL covers source code only. I would say that the GPL also covers object code, and even more so: you can distribute source without object, but not object without source. I fully agree that weights are not source code. But how a...

I've been trying to reach John Stanback to invite Wasp 3.2, but to no avail. His email address is not public.
[...]
If anyone knows how to contact John, help would be greatly appreciated.
Have you tried PM (jstanback)? John has posted here recently.
