Background. Federated Learning (FL) enables collaborative model training across decentralized data sources without sharing raw data, making it highly relevant for edge computing in emerging technologies like 6G and the Internet of Things (IoT). It supports privacy by design, as sensitive data remains on-device. However, real-world FL often struggles with heterogeneous data distributions across clients. This project addresses that challenge by exploring Conditional Federated Learning, a novel approach that combines personalized and clustered FL to better manage distribution shifts. The project is hosted by RISE Research Institutes of Sweden, a state-owned research institute that supports sustainable innovation across academia, industry, and the public sector.

Description. This thesis investigates the design and implementation of a Conditional Federated Learning framework that adapts to client-specific data distributions. The method will be tested across various tasks, model architectures, and datasets to evaluate its robustness to different types of heterogeneity. Results will be benchmarked against established FL baselines to assess performance in both accuracy and generalization.
