Asymmetric Focal Loss Boosts GNN Drug-Drug Interaction Prediction

Researchers have developed an asymmetric focal loss function to enhance the predictive accuracy of graph neural networks (GNNs) for drug-drug interactions (DDIs). This novel objective function, integrated into a relation-aware graph convolutional network, prioritizes difficult-to-classify positive interactions. When evaluated against standard binary cross-entropy, the asymmetric focal loss significantly improved key metrics including accuracy, F1 score, AUROC, and AUCPR, while substantially reducing the false-negative rate and overall classification error.
