ISCMF: Integrated Similarity-Constrained Matrix Factorization for Drug-Drug Interaction Prediction

In this study, we use Integrated Similarity-Constrained Matrix Factorization (ISCMF) to predict DDIs. Eight similarities based on the drug substructure, targets, side effects, off-label side effects, pathways, transporters, enzymes, and indication data as well as Gaussian interaction profile for the drug pairs are calculated. Subsequently, a non-linear similarity fusion method is used to integrate multiple similarities and make them more informative. Finally, we use ISCMF which projects the drugs in the interaction space into a low-rank space constrained to obtain new insight about DDIs.
