Projected gradient
WebApr 18, 2024 · This work develops a provably accurate fully-decentralized alternating projected gradient descent (GD) algorithm for recovering a low rank (LR) matrix from mutually independent projections of each of its columns, in a fast and communication-efficient fashion.

Unlike the ordinary gradient method, the subgradient method is notadescentmethod;thefunctionvaluecan(andoftendoes)increase. The subgradient method is far slower than Newton’s method, but is much simpler and can be applied to a far wider variety of problems. By combining the subgradient method

WebThe aim of this paper is to study the convergence properties of the gradient projection method and to apply these results to algorithms for linearly constrained problems. The main convergence result is obtained by defining a projected gradient, and proving that the gradient projection method forces the sequence of projected gradients to zero.
