New parameter-free optimizer AdamG simplifies hyperparameter tuning

Researchers have developed a new parameter-free optimizer called AdamG, which aims to simplify hyperparameter tuning by automatically adapting to various optimization problems. This novel approach, based on a golden step size derived for the AdaGrad-Norm algorithm, is designed to maintain tuning-free convergence and approximate optimal step sizes. Empirical evaluations indicate that AdamG performs comparably to Adam with manual learning rate tuning and surpasses other parameter-free optimizers, while also introducing a new metric called 'reliability' to better assess parameter-free optimizer performance.
