报告摘要：
Sparse representation has been a hot topic in signal processing and machine learning in recent years. In the past, people usually discussed 1D sparsity, i.e., the number of nonzeros in a vector. For 2D signals, we can actually also define a measure of sparsity, namely the rank of the data matrix. In this talk, I will give a brief history of sparse representation and then introduce some core problems and theories of rank minimization. Finally, I will show some applications of rank minimization that have resulted in improved performance in handling imperfect data that can have noise, outliers and missing values.
