Researchers have theoretically analyzed the edge-of-stability (EoS) phenomenon in the Adam optimizer, focusing on a simplified one-dimensional quadratic problem. Their work provides a dynamical explanation for Adam's EoS by proving a tendency towards a stability threshold in many parameter regimes. However, the study also identifies specific conditions, such as certain periodic orbits and tuned trajectories, where this edge-seeking mechanism fails, even when converging to the optimum. AI
