Generalized low rank models

Webproblems. We also show through simulations the bene t of using low-rank tensor regularization schemes compared to using a low-rank matrix scheme. The remainder of the paper is organized as follows: Section 2 introduces the basics of the low-rank tensor regression models we consider and introduces the projected gradient de-scent algorithm.
