Projection Algorithms for Non-Convex Minimization with Application to Sparse Principal Component Analysis

William W. Hager, Dzung T. Phan, Jia-Jie Zhu

We consider concave minimization problems over non-convex sets.Optimization problems with this structure arise in sparse principal component analysis. We analyze both a gradient pr…
