Researchers have developed a novel optimization technique called Hybrid Momentum (HyM) for deep learning models. HyM combines a linearly weighted average of past gradients with a geometrically discounted fast momentum, aiming to better retain long-term history while adapting to recent changes. A specific implementation, HyMUON, which incorporates Newton--Schulz orthogonalization, has shown improved performance over existing methods in image classification, machine translation, and language modeling tasks. Notably, HyMUON achieved better validation loss for GPT-2 124M and LLaMA-1.3B pretraining compared to the Muon optimizer. AI
