Re: Steroid Leela (2x faster leela) will be playing TCEC 20 Sufi

Is there a speedup across all backends (such as e.g. DX12)?

Re: Playing with "The Secret of Chess"

Have you by any chance tried ridge regression? No. I had to google that. And despite my mathematical background some web pages with that look too complicated. I need a cookbook example or a simple explanation for that. Don't bother. Typically I come up with some unproven and instant ideas for a bet...

Re: Playing with "The Secret of Chess"

Let me just say kudos, finally someone has done it! Actually implementing all L. Tsvetkov's eval terms and letting some ML process decide about the weights is something I've been thinking about for a long time, but unfortunately it requires much more time than I have. I find Tsvetkov's work fascinat...

Re: So what do we miss in the traditional evaluation?

Been there. Done that. (The first half without the NNUE training.) It seems you have seen the other thread Playing with "The Secret of Chess" http://www.talkchess.com/forum3/viewtopic.php?f=2&t=76453 With that I am now doing some Texel Tuning. Wow... I haven't seen that thread! I'll leave a comment...

Re: So what do we miss in the traditional evaluation?

Can we learn something from NNUE networks, using some kind of "reverse engineering" ? Maybe it's a bad idea but for example taking thousands of winning positions with passed pawns and looking at the highest values in hidden layers, then look at the inputs used to produce these values, is it possibl...

Re: correspondence chess in the age of NNUE

lower ELos simply do not use engines or do not use engines for a long time. I do not believe NNUE made a big change and I doubt if it is possible to get less than 90% draws in correspondence games against something like Stockfish10 even if you use NNUE against it assuming you use 8 hours for every ...

Re: correspondence chess in the age of NNUE

Taking out really weak players (probably not even using a computer) the draw rate for the past three years is already close to 60%. If you take out weak players, like those who only use a computer to check some positions, it raises over 75%. We're still talking over 140,000 games for just three yea...

Re: Verify integrity of Syzygy TB with MD5

I saw this as well, but I wasn't sure what I should type inside "filepath". I don't want to check all the files individualy (one by one), how can I test multiple files at the same time? And also, does this method compares the two hash (md5) files? Hope I am understood (my english is not the best) :...

Re: Verify integrity of Syzygy TB with MD5

If you're running Windows 10, the easy way (no need to download anything) is doing it in PowerShell:

Code: Select all

Get-FileHash <filepath> -Algorithm MD5

Re: Final Release of Ethereal, V12.75

Imho "choose life instead of chess programming" is a stupid remark. Something that is fun to do IS life. What if it is no longer fun for you. What then? Let me quote Slavoj Zizek: For example, let’s be serious: when you are in a creative endeavor, in that wonderful fever--“My God, I’m onto somethin...
