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.chiggate.com/eeboo-memory-matching-game-animal-pre-school-supply/
