Researchers have developed a theoretical framework for optimal learning rate schedules in deep learning, specifically analyzing a random feature model trained with stochastic gradient descent. The study identifies two distinct training regimes: an 'easy phase' where optimal schedules follow a polynomial decay, and a 'hard phase' characterized by an initial constant learning rate followed by annealing. This theoretical model outperforms existing benchmarks for learning rates and batch sizes, offering insights into how LR transferability depends on model and task structures, with experimental validation on ResNet and GPT-2 models.
