Researchers have explored physics-inspired optimizers for deep learning, focusing on their behavior beyond the stability limit. They identified period-two orbits that can maintain stability if the optimizer's elasticity is within a specific range. The study also found that delayed instability, akin to Neishtadt's theory of slowly swept bifurcations, accurately describes the dynamics in neural networks. Experiments on MLPs and ResNets support these theoretical findings, suggesting that matching effective learning rates can replicate some of the observed benefits. AI
