Web6. How does this work extend to regularized regression? 7. Line 182: How is the assumption mild? The denominator is actually big. Matrix completion is not a good reference; it's a different problem. 8. The synthetic data in the experiments are not interesting. Sampling from normal distribution ensures incoherence. WebDec 6, 2024 · We give an online algorithm and prove novel mistake and regret bounds for online binary matrix completion with side information. The mistake bounds we prove are of the form Õ(Ɗ/γ 2).The term 1/γ 2 is analogous to the usual margin term in SVM (perceptron) bounds. More specifically, if we assume that there is some factorization of the underlying …
WebApr 1, 2024 · In contrast, there doesn't seem to be such an intuition for strong incoherence. The author showed that strong incoherence is actually not required for matrix completion, which is desirable since the strong incoherence was usually the dominant factor ( μ 1 ≥ μ 0) in previous bounds. WebIn [7], it was proved 1) that matrix completion is not as ill-posed as previously thought and 2) that exact matrix completion is possible by convex programming. The authors of [7] …
