Adaptive Multilevel Newton: A Quadratically Convergent Optimization Method

Nick Tsipinakis, Panagiotis Tigkas, Panos Parpas

Newton's method may exhibit slower convergence than vanilla Gradient Descent in its initial phase on strongly convex problems. Classical Newton-type multilevel methods mitigate thi…

Convergence rates of Newton's method for strongly self-concordant minimization

Nick Tsipinakis, Panos Parpas

Newton's method has been thoroughly studied for the class of self-concordant functions. However, a local analysis specific to strongly self-concordant functions (a subclass of the…
