An Efficient Orthonormalization-Free Approach for Sparse Dictionary Learning and Dual Principal Component Pursuit

Sparse dictionary learning (SDL) is a classic representation learning method and has been widely used in data analysis. Recently, the [Formula: see text]-norm ([Formula: see text]) maximization has been proposed to solve SDL, which reshapes the problem to an optimization problem with orthogonality c...
