A random walk down NNUE street ….

Mike,

a few thoughts

1) There’s not a lot of benefit to d11 at this stage. I’d just go with d6 or d8 until your net has figured out piece values.
2) generate 1b positions per generation. More is better.
3) start with lambda 0.0 (all result) and gradually add more eval. Not sure how fast to turn the knob.

I had to add in naive material qsearch to the Harmon net as it never really learned material from lambda 0.0.

Thanks , appreciate your suggestions, Interestingly I started with eval and hybrid (0.5) first, but going forward will definitely use 0.0. That was just from observation where felt I need some eval (some help) in the beginning, I was not pleased with all result in the beginning.

Here is my latest test run against Zappa Mexico - I am pretty sure by tomorrow , I will have leap frogged over Zappa.
Error bars are huge here, but I don't need to be precise at this level, it will just slow me down.

Interesting, intuitively I'd think the opposite would be more correct.
First you train from the eval (of a previous engine or net / whatever) then you start RL with low LR and low lambda to finetune the net.

But actual empirical evidence >>> "intuition" and your stronger nets are really good.

All of the other nets I’ve trained are from the eval of some other engine. The Harmon net was the only one trained predominantly from game outcomes (as human games don’t have “evals”). Adding in naive material qsearch gave it some basic piece value sense. Otherwise it was sacrificing minor pieces and rooks like crazy. Entertaining, but more a 1600’s idea of how a GM might play.

I haven’t trained a net from scratch like Mike, but initially the eval is meaningless. Only results are of value. That changes as the generations of nets get smarter, but I’m just going by leela analogy. You’d have to use something like Cfish’s pure to avoid getting stockfish’s HCE past a threshold and getting a truly from scratch net.

I am using "pure" 100% that is built into the "nodchip" SF trainer app ( built into the Stockfish version on his github page) . Would that be the same "pure" setting?

I think so. I’ve never used sf to generate data, so perhaps not the greatest expert.

[MikeB]

So on my first pass at learning - after learning at D4 , D5, D6 through to D11 , the net tested at about 200 Elo below Zappa Mexico
A second wave of training, going from D4, D6. up to D10, has now made the net about equal to Zappa Mexico II.
Will be completing my first pass at D12 today, Willa do a second pass at D12 and then release the net publicly.

Quantum computing for chess seems to be a a long way off, if ever. I'm not expecting to see anything with my remaining days on earth, but who knows, maybe I will.

If you look at that blog post, you'll see that it has nothing to do with chess. The author is just using a bizarre analogy.

As I've said before, there is no [known] quantum algorithm for chess, and there is no reason to believe that one would exist.

Give me a billion qubits and I will do it

No, you won't.

We're not talking about implementing the program on hardware. We're just talking about writing correct code that would do the job given the hardware. There is no known algorithm.

We still have no von Neumann architecture for quantum computers, so your analogy with code/program and hardware lacks, quantum-algorithms are implemented as quantum-circuits, there is currently no quantum-code beside languages which describe these circuits, and yes - no, I will not do a paper machine with billions of qubits

Alright, seems I have to dig deeper....

"Implementing the Quantum von Neumann Architecture with Superconducting Circuits"

...
The ability to store entanglement in the memories, which are characterized by much longer coherence times than the qubits, is key to the quantum von Neumann architecture.
...

maybe I will give it a try for TicTacToe some day.

I'm not sure what you are trying to say. If you are worrying about a specific architecture, then surely you are worrying about hardware implementation.

I'm saying you won't be able to come up with an algorithm, like e.g. alpha-beta for classical computer chess. Forget about machines to run alpha-beta on. Forget about computer languages to write it in. If the "alpha-beta" does not exist, those things are irrelevant. You need the algorithm first, specified the way we can specify alpha-beta architecture-independently and language-independently.

No one has come up with an algorithm and no one will be able to.

So in which language, code, program, calculus, math you would accept my
project "Iota", a perfect play TicTacToe engine for quantum-computers?

to make my point more clear:

Quantum algorithms are usually described, in the commonly used circuit model of quantum computation, by a quantum circuit which acts on some input qubits and terminates with a measurement. A quantum circuit consists of simple quantum gates which act on at most a fixed number of qubits. The number of qubits has to be fixed because a changing number of qubits implies non-unitary evolution. Quantum algorithms may also be stated in other models of quantum computation, such as the Hamiltonian oracle model.
