GraphDiffMed: Knowledge-Constrained Differential Attention with Pharmacological Graph Priors for Medication Recommendation
GraphDiffMed is a new framework designed for medication recommendation that integrates pharmacological knowledge with differential attention mechanisms. It aims to improve the quality and safety of medication recommendations by addressing the challenges posed by noisy and heterogeneous patient data. The framework has shown promising results in experiments, outperforming existing methods in both recommendation quality and safety performance balance.
- ▪GraphDiffMed utilizes dual-scale Differential Attention to filter out noise in patient data.
- ▪The framework incorporates pharmacological constraints during the learning process.
- ▪Experiments conducted on MIMIC-III data demonstrate improved recommendation quality over strong baselines.
