Researchers have developed a formal framework to determine query identifiability in multi-view pretraining scenarios, where data from multiple sources is integrated through a shared interface. They proved that ambiguity in queries is structural and cannot be resolved by simply collecting more data or training larger models. The study introduces algorithms that can efficiently decide identifiability and find minimal interface additions to resolve ambiguity, with experiments confirming their effectiveness and predicting an irreducible error floor for estimators relying solely on interface evidence.
