WebDescription ===== The LBFGS method implements the limited-memory BFGS algorithm as described in Nocedal and Wright (sec. 7.2, 2006) and original paper by Liu & Nocedal (1989). It is a quasi-Newton method that updates an approximation to the Hessian using past approximations as well as the gradient. WebOpis projekta. U okviru ovog projekta implementirana je L-BFGS (Limited-memory BFGS) metoda optimizacije. L-BFGS pripada kvazi-Njutnovim metodama optimizacije drugog reda, i kao što joj ime kaže, predstavlja modifikaciju BFGS (Broyden–Fletcher–Goldfarb–Shanno) metode optimizicije koja koristi manje memorije. To se postiže uklanjanjem ...
