Definition

Matrix regularization extends scalar regularization concepts to matrices, often used in multi-task learning or recommendation systems. It imposes constraints on the norm of weight matrices, such as the Frobenius norm or nuclear norm, to control model complexity. This helps in reducing overfitting by discouraging large weights and can enforce low-rank structures, which is beneficial for capturing latent factors in data. It ensures that the learned representations remain stable and interpretable.
