Researchers have presented a new finite-time analysis for the Adam optimizer, addressing its convergence in nonsmooth nonconvex optimization problems. This work is significant because it analyzes the classical form of Adam, including its bias-correction term and without requiring additional modifications like clipping. The study proves that a randomly scaled learning rate can achieve a convergence rate of $1/T^{ rac{2}{13}}$ for nonsmooth nonconvex optimization, a finding that extends to the modern heavy-tailed noise regime relevant to practical applications.
