Adaptive Optimization

Adaptive optimization aims to improve the efficiency and effectiveness of training machine learning models by dynamically adjusting optimization parameters based on the data and model's behavior. Current research focuses on enhancing existing algorithms like Adam, developing memory-efficient variants (e.g., MicroAdam), and adapting them for distributed settings such as federated learning, often incorporating techniques like sparsification and momentum adjustments to reduce communication overhead and improve convergence. These advancements are significant for scaling machine learning to larger datasets and more complex models, impacting fields ranging from natural language processing and computer vision to robotics and resource-constrained environments.
