Optimal Learning Rate Schedules Explored Under Functional Scaling Laws

This paper explores optimal learning rate schedules for machine learning models, particularly within the Functional Scaling Law (FSL) framework. It identifies a critical transition point based on task difficulty and model capacity, dictating whether an early power decay or a warmup-stable-decay schedule is more effective. The research also suggests that precise decay shape tuning may be less critical than previously thought, with fractional schedules achieving optimal convergence rates. AI
