L1 Norm是将所有参数的绝对值之和作为正则项,L2 Norm是将所有参数的平方和作为正则项。L1对outlier更Robust,且有稀疏性;L2计算起来更方便,且有唯一解。 Lasso / Ridge 的解释(Prior分别是什么) Lasso是指加入系数的L1 Norm作为正则项,而Ridge是加入系数的L2 Norm作为正则项。L1的prior是认为参数w的先验概率满足...

1. 矩阵范数的等价性 (Equivalence of Matrix Norms)对于任意两个矩阵范数||\cdot||_\alpha和||\cdot||_\beta,存在常数m,M>0,使得对于所有矩阵A,都有m||A||_\alpha \leq ||A||_\beta \leq M||A||_\alpha.(证明从略,与上一节中向量范数的等价性证明类似.)2. 相容范数 (Compatible Norm...
The norm ja:math of the alias matrix A of a design can be used as a measure for selecting a design. In this paper, an explicit expression for ‖ A ‖ will be given for a balanced fractional 2 m factorial design of resolution 2 l + 1 which obtained from a simple array with paramete...
Matrix energy(0,1)-matrixSingular valuesThe trace norm of a matrix is the sum of its singular values. This paper presents results on the minimum trace norm $\\\psi_{n}\\\left( might) $ of $\\\left( 0,1ight) $-matrices of size $nimes n$ with exactly $m$ ones. It is shown...

Traditional PCA is sensitive to outliers and feature noises, PCA based on L2, 1-norm can improve the problems. Whereas present L2, 1-PCA algorithms implement dimension reduction on the rank of the matrix and the rank is complex problem. In order to solve this problem, this paper proposed us...
