I considered the idea of representing players via vectors in different context (chess, soccer, mma) and also worked a bit on splitting the evaluation of moves into “quality” and “risk taking”, with the idea of quantifying aggression in chess.
My impression is that the single scalar rating works really well in chess, so I’m not sure how much there is beyond that. However, some simple experiments in that direction wouldn’t be too difficult to set up.
Also, I think there were competitions on creating better rating systems that outperform Elo’s predictiveness (which apparently isn’t too difficult). But I don’t know whether any of those were multi-dimensional.
ELO is the Electric Light Orchestra. The Elo rating is named after Prof. Arpad Elo.
