Web24 jun. 2024 · A quick way to see that the Frobenius norm of A is the 2-norm of the vector of singular values uses the orthogonal invariance of the Frobenius norm. Start by taking the SVD of A A = U Σ V T So ‖ A ‖ F = ‖ U Σ V T ‖ F. Since the Frobenius norm is … Web28 jan. 2024 · We find that all linear performance leaders effectively add only a nuclear-norm based regularizer, or a Frobenius-norm based regularizer. The former ones possess a (surprisnig) rigid structure that limits the models' predictive power but their solutions are low rank and have closed form.
