Federated Explainable Artificial Intelligence: Roles, Architectures, Evaluation, and Open Challenges
Short summary
This survey systematically reviews Federated Explainable AI (FedXAI), the intersection of privacy-preserving federated learning and explainable AI. It introduces a taxonomy classifying methods by the role of explainability, model types, explanation scope, integration level, FL settings, and data heterogeneity. The authors identify key open challenges including explainability under non-IID data, explanation-centric security threats, and the lack of standardized benchmarks for measuring explanation quality and privacy leakage in federated settings.
- •Comprehensive survey of Federated Explainable AI (FedXAI) with a structured taxonomy
- •Covers transition of explainability from post-hoc tool to integral FL lifecycle component
- •Identifies open challenges: non-IID explainability, security threats, missing benchmarks
Generated with AI, which can make mistakes.
