Report on Current Developments in Federated Learning for Manufacturing
General Direction of the Field
Federated Learning (FL) continues to evolve as a critical paradigm for training machine learning models in decentralized environments, particularly in manufacturing and shared production settings. Recent developments highlight a concerted effort to address the inherent challenges posed by data heterogeneity across different clients and production sites. The field is moving towards more adaptive, scalable, and robust solutions that ensure efficient and fair model training in the face of non-independent and identically distributed (non-IID) data, unbalanced data, variable data quality, and statistical heterogeneity.
Innovative methodologies are being explored to mitigate the adverse effects of data heterogeneity. These include personalized and customized models, robust aggregation techniques, and sophisticated client selection strategies. The integration of new clients into existing FL systems is receiving significant attention, with a focus on enhancing data diversity and improving system stability and scalability. Additionally, the selection of client weights for server aggregation is being rigorously studied to optimize model performance and robustness, especially in contexts with a limited number of participating clients.
The field is also addressing the issue of fairness in client selection, with novel approaches leveraging submodular function maximization to achieve more balanced and equitable outcomes. These developments are crucial for advancing FL in Industry 4.0, where equitable and efficient training across diverse environments is paramount.
