Supplementary Material of Modeling the Uncertainty of Contextual-Connections between Tracklets for Unconstrained Video-based Face Recognition

where Tgt and Ttt are corresponding temperature factors, k ∈ {0, 1}, αp is the positive penalty and αn is the negative penalty. Directly looking for the label assignment that minimizes E(x,y) is a combinatorial optimization problem which is intractable. Instead, similar to [9], we use mean field method to approximate the distribution P (X,Y) ∝ exp(−E(X,Y)) by the product of independent marginals
