Fig. 3From: A unified solution for different scenarios of predicting drug-target interactions via triple matrix factorizationIllustration of cross-validation schemes for four scenarios. Each column accounts for a scenario. The first row contains the DTI matrices, in which the entries marked with “?” are the pairs of interest to be tested. Especially, the entries marked with “-” in S4 attend in neither training nor testing phases. The second row contains the topologies of the pairs of interestBack to article page
