Suppose classifier AvsBC assigns x a posterior probability Pr (A) = 0.51. Under this result the ensemble would presumably stop, and never explore the other options, and thus might miss out on higher posterior probability assignments (e.g., under BvAC you might get Pr (B) = 0.60). spicy berbere lentil chili
