"We studied the problem of sparse subspace tracking in the\r\nhigh-dimensional regime where the dimension is comparable\r\nto or much larger than the sample size. Leveraging power iteration and thresholding methods, a new provable algorithm\r\ncalled OPIT was derived for tracking the sparse principal subspace of data streams over time. We also presented a theoretical result on its convergence to verify its consistency in high dimensions. Several experiments were carried out on both synthetic and real data to demonstrate the effectiveness of OPIT."^^ . . . . . . . . . . . . . . . . . "Trung Thanh"^^ . "Le"^^ . "Trung Thanh Le"^^ . .
