New RAMPAGE method offers unbiased gradient extrapolation for variational inequalities

Researchers have introduced RAMPAGE, a novel method for solving Variational Inequalities (VIs) that addresses discretization bias inherent in the Extragradient (EG) method. RAMPAGE and its variance-reduced counterpart, RAMPAGE+, offer unbiased solutions and achieve provable convergence guarantees for various problem types. RAMPAGE+ further improves upon RAMPAGE by leveraging antithetic sampling to eliminate internal first-order terms from the variance, acting as an unbiased geometric path-integrator. AI
