Web10 ago 2024 · In this paper we study nonconvex and nonsmooth multi-block optimization over Euclidean embedded (smooth) Riemannian submanifolds with coupled linear constraints. Such optimization problems naturally arise from machine learning, statistical learning, compressive sensing, image processing, and tensor PCA, among others. http://export.arxiv.org/abs/2211.02163 how cook scallops in ovenWebRiemannian versions of the subgradient method have been studied in [5, 10]. In [14], a nonsmooth trust region method is generalized on Riemannian manifolds. The work [24] is concerned with the manifold alternating directions method of multipliers (MADMM), which can be seen as an extension of the classical ADMM scheme for manifold constrained non- how cook scallops in pan
