CNN for Go at least seems justifiable. The use of a convolution captures the fact that a configuration of stones is mostly the same configuration of stones whether or not you shift it around the board a little bit.
This is much less true for chess, although it might still be true enough.
- dragontamer 7y agoThere are a lot of configurations of pawns or knights that are highly desirable. A "knight outpost" (a knight guarded by a a pawn) is a "local" board position that is well considered to be strong. Same with a bishop outpost. "Paired knights" (knights which can protect each other) can only rarely be taken by a rook or queen. Pawn-chains are good, while "backwards pawns" and "doubled pawns" are bad. "Rook behind pawn" is good, "Rook in front of pawn" is bad. King Opposition is good (https://en.wikipedia.org/wiki/Opposition_(chess) https://en.wikipedia.org/wiki/Opposition_(chess)) Go is more uniform for sure. But there are plenty of opportunities for CNNs to work out in chess.
