1. L0 norm First, L0 norm is actually not a norm, because it does not obey the rules for norm() Then, knowing that the L0 norm of a matrix is just the number of non-zero terms in the vector is enough. So we can say that L0 norm represent the sparsity of a vector, if x ...
向量长度(length of a vector)又叫做向量模(vector norm)、欧几里得距离(Euclidean distance)、欧几里得范数(Euclidean norm)或L2范数(L2-norm)。给定向量a为向量a的模为注意:的下角标2代表L2范数。没有特殊说明,默认代表L2范数。L2范数是Lp范数的一种,本书第3章将介绍其他范数。
Face recognition is one of the most active research areas in computer vision and pattern recognition with practical applications. This work proposes an apperence based Eigenface technique. PCA is used in extracting the relevant information in human faces. In this method the Eigen vectors of the set...

can be a vector or a matrix. For example, a Euclidean norm of a vector is which is the size of vector The above example shows how to compute a Euclidean norm, or formally called an -norm. There are many other types of norm that beyond our explanation here, actually for every singlere...
Mathematically a norm is a total size or length of all vectors in a vector space or matrices. For simplicity, we can say that the higher the norm is, the bigger the (value in) matrix or vector is. Norm may come in many forms and many names, including these popular name:Euclidean dist...
