Figure 4From: CRF-based models of protein surfaces improve protein-protein interaction site predictionsViterbi recursion step in case v∉ ℬ tmp . After adding node v to the history set, ℋ 2 and ℋ 3 will be replaced by ℋ tmp = ℋ 2 ∪ ℋ 3 ∪{v}. In this example, for every assignment of the new boundary ℬ tmp the score of ℋ tmp is maximized by varying over the assignments of v and R 3 and using the Viterbi variables of ℋ 2 and ℋ 3 .Back to article page
