Modeling AdaGrad, RMSProp, and Adam with Integro-Differential Equations
Researchers have developed a continuous-time framework to model popular optimization algorithms like AdaGrad, RMSProp, and Adam. By representing these algorithms as integro-differential equations, the study provides a new theoretical lens for understanding their behavior. Numerical simulations and convergence analyses confirm that these continuous-time models accurately approximate the original discrete algorithms, offering deeper insights into adaptive optimization methods.
