Towards Fully Explainable Federated Learning
摘要
This chapter outlines a practical path toward fully explainable FL: we connect client-level attributions and visual explanations (e.g., LayerCAM-based heat maps) with representation-level diagnostics and lightweight, server-side screening that informs aggregation, fairness, and privacy decisions. Emphasizing deployment-ready tools with minimal overhead, we show how explainability improves robustness to poisoning, accelerates convergence under Non-IID data, and supports energy- and carbon-aware orchestration, thereby turning transparency from a reporting afterthought into a core mechanism for trustworthy FL.
