Spectral normThis study focuses on the exponentially weighted moving sample covariance matrix (EWMV), investigating its behavior in both null and alternative hypotheses. Under the null hypothesis, assuming normal observations, we establish exponential probability bounds for the largest eigenvalue. Similarly...
于是在文献[4]中作者提出了 Spectral Norm,对网络参数进行谱归一化使得网络满足利普希茨连续条件。 矩阵的奇异值分解 (Singular Value Decomposition) 为了方便大家理解 Spectral Norm ,我们先介绍一下 SVD 分解。 假设有 $m\times n$ 的方阵 $A$,对矩阵 $A$ 存在这样一种分解: \begin{equation} \mathbf{A}...
In this paper, both well-known and new properties of the spectral abscissa and the logarithmic norm are described. In addition to well-known formulas for the norm of a matrix and for its logarithmic norm in cubic, octahedral, spherical norms, various estimates for these quantities in an arbitr...
从上式可以看出,L2正则要求矩阵W所有的奇异值都减小,而Spectral Norm Regularization只要求减少最大的奇异值。 对抗训练考虑如下问题: \operatorname{minimize}_{\Theta} \alpha \cdot \frac{1}{K} \sum_{i=1}^{K} L\left(f_{\Theta}\left(\boldsymbol{x}_{i}\right), \boldsymbol{y}_{i}\...
摘要: In this paper, we introduce some ratios between the numerical radius and the spectral radius of a matrix and the square root of the spectral norm of the square of this matrix, and we review the existing results for extreme cases....
