Select all the true statements about KSVD. KSVD dictionary learning is performed by repeating two steps, dictionary pursuit for sparse signal representation and dictionary updates. OKSVD is a greedy algorithm and is not guaranteed to converge to an optimal solution. The dictionary update preserves the sparsity of the representation by operating on only a single dictionary vector at a time and then only updating based on data vectors that use that vector. The KSVD algorithm creates a dictionary of vectors by selecting the columns of the V matrix from the SVD of the data matrix, A = UVT, that provide the best sparse approximation of the vectors in the data matrix. The KSVD algorithm learns an orthonormal basis that can be used to represent training signals in a sparse manner.
