웹Barzilai and Borwein [1], the convergence for quadratics was established by Raydan [17], and more recently, a proof of the R-linear rate of convergence for convex quadratics was given by Dai and Liao [10]. A complete review is presented by Fletcher [11], and the asymptotic behavior is studied by Dai and Fletcher [9]. 웹2024년 11월 3일 · Quadratic regularization projected Barzilai–Borwein method for nonnegative matrix factorization.
