Layer Freezing

Layer freezing is a technique to accelerate deep learning model training by selectively deactivating certain layers during the training process. Current research focuses on developing intelligent methods to determine which layers to freeze, employing strategies such as semantic analysis of model behavior, attention mechanisms, and knowledge transfer from reference models to identify layers that have converged and can be safely deactivated. This approach offers significant potential for reducing training time and computational costs, particularly relevant for large language models and other computationally intensive deep neural networks, thereby improving the efficiency and accessibility of deep learning applications.
