Federated Deep Learning for Secure and Decentralized Model Training

Abstract: Federated deep learning (FDL) is an emerging paradigm that enables multiple decentralized devices or institutions to collaboratively train a shared model while keeping data localized. This approach preserves privacy, reduces communication overhead, and complies with data governance regulations. In this paper, we explore the implementation and performance of FDL in real-world scenarios such as healthcare, finance, and IoT systems. Utilizing frameworks like TensorFlow Federated, PyTorch, and interpretability tools like SHAP and LIME, we evaluate FDL against centralized deep learning models. We analyze convergence rates, model accuracy, data privacy risk, and computational efficiency. Regression and predictive analyses reveal that FDL can retain over 90% accuracy of centralized models with significantly enhanced data security.
