Gradient Clipping

Gradient clipping is a technique used in training machine learning models, particularly deep neural networks, to constrain the magnitude of gradients during optimization. Current research focuses on improving the theoretical understanding of gradient clipping's impact on convergence, especially in scenarios with heavy-tailed noise or non-convex loss functions, and exploring its application in distributed and differentially private settings. This technique is significant because it enhances the stability and robustness of training, leading to improved model performance and enabling privacy-preserving machine learning. Furthermore, research is exploring adaptive clipping strategies to optimize performance across various model architectures and datasets.
