Identification Lower Bound
In test-time ensemble learning, an error lower bound that reflects the identifiability limits of the model's answer distribution itself. It is independent of the number of questions, and cannot be breached even if the number of questions is infinite.

Mechanism three: when the number of questions is sufficiently large, the minimax excess risk reaches the identification lower bound of N^{-β}, which cannot be broken even with infinitely many questions, and this lower bound is independent of the number of questions.
