New optimization method Local LMO bypasses projections

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced Local LMO, a novel projection-free gradient method for constrained optimization problems. This method replaces the global linear minimization step of Frank-Wolfe with a local one within a small ball around the current iterate. Local LMO offers convergence rates comparable to Projected Gradient Descent in various settings, including scenarios where the constraint set is unbounded, and achieves linear rates for smooth strongly convex functions.

    Local LMO: Constrained Gradient Optimization via a Local Linear Minimization Oracle

    We design Local LMO - a new projection-free gradient-type method for constrained optimization. The key algorithmic idea is to replace the global linear minimization oracle over the constraint set used by Frank-Wolfe (FW) with a local linear minimization oracle over the intersecti…
