Abstract:

Optimization with nonnegative orthogonality constraints, which includes both nonnegative constraints and orthogonality constraints, has important applications in machine learning and data science. Some typical instances of optimization with nonnegative orthogonality constraints include the quadratic assignment problem, graph matching problem, orthogonal nonnegative matrix factorization problem, nonnegative principal component analysis, and K-indicator model, etc. Due to the coupling effects of nonnegative and orthogonal constraints, this type of problem has a certain combinatorial structure and is generally NP-hard. This paper mainly introduces the basic theoretical properties, algorithms, and related applications of optimization with nonnegative orthogonality constraints.

Key words: optimization with nonnegative orthogonality constraints, optimization with permutation matrices constraints, exact penalty, ?p regularization, quadratic assignment problem
