Researchers have introduced the Sharpness-aware Orthogonalized Momentum Algorithm (SOMA), a new optimization technique designed to improve the generalization and robustness of large language models (LLMs). SOMA combines a computationally efficient perturbation scheme with the Muon algorithm, utilizing stale stochastic gradient noise for adversarial perturbations. This approach aims to mitigate the prohibitive cost of traditional sharpness penalties in LLMs. The paper theoretically demonstrates that SOMA's sample complexity is invariant to perturbation direction and explores its effectiveness in reducing quality degradation from post-training quantization and preventing catastrophic forgetting during LLM fine-tuning.
