Clinical Report: Asynchronous Proximal Federated Aggregation Framework for Diverse Healthcare Networks
Overview
The Asynchronous Proximal Federated Aggregation (APFA) framework addresses computational asymmetry and statistical heterogeneity in Federated Learning (FL) for healthcare. APFA achieved an 80% diagnostic viability threshold in 4.1 simulated hours.
Background
The integration of Internet of Medical Things (IoMT) devices in healthcare has transformed patient monitoring and diagnostics but poses challenges in data privacy and computational efficiency. Federated Learning (FL) offers a decentralized approach to machine learning, allowing for local data processing while preserving privacy. However, the deployment of FL in heterogeneous healthcare settings is complicated by variations in device capabilities and non-IID data distributions.
Data Highlights
No numerical data table available.
Key Findings
- APFA integrates a local proximal regularizer and server-side staleness dampening penalty.
- APFA reached an 80% diagnostic viability threshold in 4.1 simulated hours.
- This represents a 71% reduction in total wait time compared to standard synchronous baselines like FedProx.
- The framework effectively mitigates weight divergence in model updates.
Clinical Implications
The APFA framework allows for faster model updates while maintaining patient data privacy.
Conclusion
The APFA framework addresses the challenges of deploying Federated Learning in heterogeneous healthcare networks.
