A new research paper explores whether federated training, a privacy-preserving method for training AI models, degrades the explainability of deepfake detection systems. The study found that while federated models can sometimes match or exceed the faithfulness of centralized models, extreme data heterogeneity among clients can cause explanations to break down entirely, becoming misleading. The research offers guidance on identifying when federated deepfake detection can be deployed safely and when its explanations should not be trusted. AI
IMPACT Federated learning may introduce explainability issues in AI models, impacting trust and deployment in sensitive applications like deepfake detection.
