An exact penalty approach for optimization with nonnegative orthogonality constraints
Abstract Optimization with nonnegative orthogonality constraints has wide applications in machine learning and data sciences. It is NP-hard due to some combinatorial properties of the constraints. We first propose an equivalent optimization formulation with nonnegative and multiple sp...
