Inourpaper theGrassmannian21 structure is utilized together with the RRC to analyze the convergence of the projected Riemannian subgradient22 method. Since33 both the robust subspace learning and dictionary learning problems are regular, their Riemannian subdifferentials34 computedinSection4arecorrect.
