Figure 2From: Conditional random field approach to prediction of protein-protein interactions using domain informationMarkov random field model for protein-protein interactions Left: Example of proteins P i and P j . P i consists of domains D1 and D2, and P j consists of domain D3, respectively. Right: Factor graph G(U,V,E). There exists an edge between P ij ∈ U and D mn ∈ V if and only if D mn ∈ P ij .Back to article page
