Subspace Clustering by Block Diagonal Representation

block diagonal property of the solutions. The block diagonal property of many existing subspace clustering methods falls into our special case. Second, we observe that many existing methods aim to approximate the block diagonal representation matrix by using different structure priors, e.g., sparsity and low-rankness, which are indirect methods.
