Manifold Proximal Point Algorithms for Dual Principal Component Pursuit and Orthogonal Dictionary Learning

Shixiang Chen, Zengde Deng, Shiqian Ma +1

We consider the problem of maximizing the $ℓ_{1}$ norm of a linear map over the sphere, which arises in various machine learning applications such as orthogonal dictionary learnin…
