3. Preliminaries and Notations
Herein, different from the typical setting of existing works, we are interested in a more challenging problem of graph clustering with unknown cluster number. Some preliminary concepts and notations are introduced here.
Throughout this paper, the lowercase boldfaced x and uppercase X denote vector and matrix, respectively. The notation table is given in Appendix C.1.
