FLARE: Detection and Mitigation of Concept Drift for Federated Learning based IoT Deployments

no code implementations15 May 2023 Theo Chow, Usman Raza, Ioannis Mavromatis, Aftab Khan

In order to simultaneously reduce communication traffic and maintain the integrity of inference models, we introduce FLARE, a novel lightweight dual-scheduler FL framework that conditionally transfers training data, and deploys models between edge and sensor endpoints based on observing the model's training behaviour and inference statistics, respectively.
