Web6 apr. 2024 · L-BFGS, two loop recursion algorithm to compute the product between B_k and a direction. Let B k be the approximated Hessian computed with the L-BFGS … Limited-memory BFGS (L-BFGS or LM-BFGS) is an optimization algorithm in the family of quasi-Newton methods that approximates the Broyden–Fletcher–Goldfarb–Shanno algorithm (BFGS) using a limited amount of computer memory. It is a popular algorithm for parameter estimation in machine learning. … Meer weergeven The algorithm starts with an initial estimate of the optimal value, $${\displaystyle \mathbf {x} _{0}}$$, and proceeds iteratively to refine that estimate with a sequence of better estimates L-BFGS … Meer weergeven Notable open source implementations include: • ALGLIB implements L-BFGS in C++ and C# as well as a separate box/linearly constrained version, BLEIC. • R's optim general-purpose optimizer routine uses the L-BFGS … Meer weergeven • Liu, D.
