Exciting news! @prof_grimmer, an assistant professor in the Department of Applied Mathematics and Statistics has proven that taking periodic long steps is actually more effective in achieving convergence! This is huge!😲 #Research #AMSProfessor #viral #PeriodicLongSteps #GoHop

I've proven the strangest result of my career.. The classic idea that gradient descent's rate is best with constant stepsizes 1/L is wrong. The idea that we need stepsizes in (0,2/L) for convergence is wrong. Periodic long steps are better, provably. https://t.co/Yqe5PUKgxI
