The Structure and Organizations of ICHD-3 Differential Diagnoses through DiffNet: A Pilot Study
2022 · Diagnostics
Differential diagnosis is fundamental to medicine. Using DiffNet, a differential diagnosis generator, as a model, we studied the structure and organization of how collections of diagnoses (i.e., sets of diagnoses) are related in the ICHD3. …

FedMDKGE: Multi-granularity Dynamic Knowledge Graph Embedding in Federated Learning
2025 · International Journal of Computational Intelligence Systems
As knowledge is time-sensitive, some researchers have started to focus on dynamic knowledge graphs to provide time-dimensioned knowledge content thus reflecting richer information. But they have not yet combined temporal information at different granularities. Also, …
