Incoherence condition 证明
Webincoherence condition: 分析这些条件可以发现， \(U,V\) 的每一行的模都不能太大， \(UV^*\) 的每个元素同样不能太大，所以最后结果 \(L_0\) 的各个元素的大小会比较均 … Webmeasurement preserving the sparsity level of an input vector. The mutual incoherence condition for the OMP is formally described in the following theorem. Theorem 1 (Mutual incoherence condition for OMP): For any K-sparse vectorx, the OMP algorithm perfectly recovers x from the measurements y = Φx if the coherence parameter µ satisfies µ ...

WebThe conditions for success of these methods are now well-understood: (1) exact recovery in the noiseless setting is possible if and only if the design matrix X satisfies the ... ates, and hence covers many matrices for which restricted isometry or incoherence conditions fail to hold but the restricted eigenvalue condition holds. Interestingly ... WebIncoherence-Optimal Matrix Completion. Abstract: This paper considers the matrix completion problem. We show that it is not necessary to assume joint incoherence, which is a standard but unintuitive and restrictive condition that is imposed by previous studies. This leads to a sample complexity bound that is orderwise optimal with respect to ...

Webincoherence condition (3) is restrictive and unintuitive. In many cases, 1 is as large as 2 0r, so previous results require O(nr2polylog(n)) observations even if 0 = O(1). In the following main theorem of the paper, we show that the joint incoherence is not necessary. The theorem only requires the weak incoherence condition. Theorem 1. WebDec 18, 2008 · We extend the idea of regularization using the Lasso, to the case of an additive model with p components, p being larger than the sample size n. Our method has a group Lasso type structure, and penalizes non-smoothness of the components in the additive model. To arrive at a sparsity oracle in- equality, we need an incoherence …
