Re: Chess.com 2018 computer chess championship

I don't understand. If I add Leela's points in the cross table I get 7 points instead of 8...

Re: 7-men Syzygy attempt

Contrary to previous versions of the bases which took on the names of their creators, de Man chose to call them Syzygy (pronounced Sih-Zih-Gee), which means a pair of connected or corresponding things. Recall that RdM is a mathematician. A syzygy is in fact a specific (somewhat advanced) mathematic...

Re: Leela is more Chess-domain specific than regular Chess engines

It's a bit disappointing but not unexpected.

If a NN is confronted with a type of data different from what it is trained on, it will fail spectacularly.

Re: how will Leela fare at the WCCC?

Not sure if the result against K12.1 is really disappointing. The error bars indicate that both engines could still be equal strength...

Re: LCZero: Progress and Scaling. Relation to CCRL Elo

Guess what, why this happens is probably because of those who have a clue about how it may work probably wouldn't bother to argue with those self-complacent experts in the future way of developing chess engines. Come on. This is unfair. Lcero is the first public NN+MCTS engine. So nobody "has a clu...

Re: Bad day at the stock market?

Contributing users play >100,000 games per day so there should be sufficient significance to rule out any weird statistical explanations. I _think_ the training window is 500,000 games. So it may take a while before the effect of corrupted training data become visible. On the list of existing netwo...

Re: Bad day at the stock market?

I don't see how a larger network can lead to better play all by itself. It will first have to be trained. I
I think it was trained for a while (using the existing training data) before it was released.

Re: Lczero stalled in progress?

I think the developers of Leela Chess Zero should learn methodology from the developers of Stockfish. The success of Stockfish originates mainly from its systematical development. That is easier said than done. The feedback loop of lczero is much longer than that of SF since it passes through the t...

Re: MCTS with minmax backup operator?

This is going to annoy you more but I am going to repeat: Whether it is a good/bad policy NN, it is going to fail. It better be good, but even in that case it is going to fail because traps are very common in chess. It doesn't annoy me :-) I just find your argument not as compelling as you do. But ...
