Formally, we define the set Z = {z (i) : The predictions of algorithms that use the mean weight vectorŷ = arg max z µ • Φ(x, z) are invariant to the value of the input Σ (as noted by ).
as before, the confidence estimation methods (KD-PC, KD-Fixed, KBV, WKBV and CRF) were applied on the entire set of predicted labels.
