New scaling law reveals SignSGD's advantages over SGD

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a functional scaling law (FSL) to understand how SignSGD, an optimization algorithm, performs compared to standard SGD. The FSL reveals that SignSGD's learning dynamics involve both signal learning and noise forgetting, with gradient noise enabling a form of preconditioning that can lead to faster signal learning. This mechanism allows SignSGD to achieve better data efficiency in challenging tasks and maintain efficiency at larger batch sizes, potentially requiring fewer optimization steps. AI

IMPACT Provides a theoretical framework for understanding and potentially improving optimization algorithms used in large-scale machine learning.

    When and How SignSGD Outperforms SGD: A Functional Scaling Law Perspective

    We study how the sign operator interacts with gradient noise to shape the learning dynamics and scaling behavior of sign-based optimizers. In power-law kernel regression with diagonal features, we establish a functional scaling law (FSL) for SignSGD under general learning rate sc…
