Global Gradient

Global gradient computation in federated learning (FL) focuses on efficiently aggregating gradients from distributed devices to train a shared model while preserving data privacy. Current research emphasizes developing algorithms that reduce communication overhead and memory requirements, often employing techniques like forward-mode auto-differentiation, approximated Hessian methods, and adaptive gradient approaches (e.g., AdaGrad, Adam) to improve convergence speed and accuracy. These advancements are crucial for enabling FL across resource-constrained devices and diverse data distributions, with significant implications for deploying large-scale machine learning models in various applications, including medical imaging and natural language processing.
