If all entries are observed, Nk = r + 1 is necessary and sufficient (assuming generic columns). If. ` = r + 1 (the minimum required), it is easy to see that.

For instance, if we have images of several faces under varying illumination conditions, then data will be lying in a union of multiple 9-dimensional subspaces.
This paper considers the subspace clustering problem where the data contains irrelevant or corrupted features. We propose a method termed “robust Dantzig se ...
