Re: First success with neural nets

Right now I. 'm using floating points with some SIMD. I estimate it could be about 3 times faster if I change to 16-bit fixed point with SIMD and add incremental updates for changing inputs on the first layer. After optimization I might play with net size and inputs to see if what works best. If yo...

White vs Black: +952 -438 =610 [0.628] 2000 There are also unprotected pawns in the beginning. I've also tested Gothic Chess. (Capablanca but different start p...
