Researchers have introduced a new framework called the "metagame" to quantify second-order interaction effects in model explanations. This framework measures the directional influence of one feature's attribution on another's by treating the attribution method as a cooperative game and calculating its Shapley value. The metagame theoretically shows that attributions can be hierarchically decomposed into meta-attributions and empirically demonstrates its utility in analyzing token interactions in language models, cross-modal similarities in vision-language models, and concepts in text-to-image transformers.
