The problem with machine learning for game AI is how expensive it is computationally. Forget about using the GPU for it. Maybe if TPUs became more common.
I think it should be possible to make, not a good one, but certainly a much better one, with a combination of various classical game tree search techniques, it's just that AI doesn't seem to have been a huge priority for the developers. There are even mods for Civ 5 that drastically improve the vanilla AI just through tweaking various behaviours.

- mtlmtlmtlmtl 4y agoMaybe, but you'll still be pretty damn limited in terms of access to the GPU. Games generally tend to push the graphics to the limit. You could make a graphically very simple game and put most of your GPU compute into AI. I'd be interested in seeing a space like that explored for sure. For graphics intensive games though, you either want something that can get by on the CPU or in future maybe TPUs will become common enough in consumer PCs so you could offload your AI onto that and still keep the GPU for fancy graphics.
