Re: Has Stockfish NNUE reached it's limit now?

Look at the learning graphs on page 4: https://arxiv.org/pdf/1712.01815.pdf Yes, it is the normal behavior and most NN learning graphs look like that. However, that is for the particular net parameters of that training run. There are many hyper-parameters that change from one net to another. A some...

Re: A different way to develop chess engines

The idea is that the test suite is not going to be WAC 300 but based on the positions that the engine went wrong... I think you missed my point.

Re: A different way to develop chess engines

Your approach has indeed been done for several decades.
