We study the multimodal and mixmodal data-driven supervised structural sparse subspace learning problem in this paper. and present the α-structural regularization based hierarchical locality analysis (α-SRHLA) model. Unlike most existing sparse subspace learning models that merely constrain the cardinalities of the subspace basis vectors. the present α-SRHLA model... https://www.nacrack.com/flash-deal-Diamond-Painting-Zee-en-strand-special-find/
