This video (series) provides a beautiful introduction to neural networks:

Thanks for the link!
And soon , RMzero
Cool for A V D

If you want to follow the Alpha zero approach you can only reuse the move generator and the user interface. Search need to be replaced and evaluation code is not used. Maybe board representation need to be optimized too. Perhaps using only bit boards is good enough.
A lot of work. Also complicated stuff. Hi hi hi . I'm getting mad. The time I'm finished they have invented something much and much better.
But isn't that with all software. It only lasts a few years and then it's totally out of date.

True. I think the speed of the moveGenerator and the underlying board representation isn't that important when you are "bottlenecked" by the NN (in terms of speed)

My move generator also sorts the moves. But that makes no sense anymore.
Evaluating a connection in a neural network is most expensive operation. Can't do much about that to speed it up. Maybe removing redundant nodes. Weight decay.

Thank you!
I know a bit about computers and a bit about chess, and have dabbled a little with computer chess engines.
With all this talk of AlphaZero and viewing a lot of video and comments about AlphaZero, I never saw anything that tried to describe neural networks. After viewing this video, I now have an idea of what a neural network is!
