Researchers have developed a new "rod flow" model to better understand how adaptive gradient optimization methods, like Adam, operate at the edge of stability. This model extends previous work on gradient descent to include momentum-based methods, treating optimization iterates as a one-dimensional "rod." The new framework accurately tracks discrete iterates for eight different optimizers, including Adam and RMSProp, across various machine learning architectures. AI
