WebThis paper proposes a novel regularization method referred to as truncated Frobenius norm (TFN), and presents a hybrid truncated norm (HTN) model combining the truncated nuclear norm and truncated Frobenius norm for solving matrix completion problems. To address this model, a simple and effective two-step iteration algorithm is designed. Web24 sep. 2024 · We have the following theorem. Theorem 7.2. The nuclear norm, the 1-norm, the Frobenius norm are tensor norms, but the infinity norm and the spectral norm are not tensor norms. Proof By Theorem 2.1, the nuclear norm is a tensor norm. Since the infinity norm is not a matrix norm, it is also not a tensor norm.
