New insights in smoothness and strong convexity with improved convergence of gradient descent
Lu Zhang, Jiani Wang, Hui Zhang
The starting assumptions to study the convergence and complexity of gradient-type methods may be the smoothness (also called Lipschitz continuity of gradient) and the strong convex…
