VECTOR_NORM(vector_column,norm_type) 参数 vector_column 计算结果为向量的表达式。 此列必须是新的向量数据类型 norm_type 一个字符串,其名称为用于计算给定向量的规范类型。 支持以下规范类型: norm1- 1-norm,它是矢量组件的绝对值之和。 norm2- 2-norm,也称为 Euclidean Norm,它是矢量分量平方和的平方根...
本文简要介绍python语言中 torch.linalg.vector_norm 的用法。用法:torch.linalg.vector_norm(A, ord=2, dim=None, keepdim=False, *, dtype=None, out=None)→ Tensor参数: A(Tensor) -张量,默认为展平,但可以使用 dim 控制此行为。 ord(int,float,inf,-inf,'fro','nuc',可选的) - 规范的顺序。

VECTOR_NORM returns the Euclidean norm of a vector (SQRT(SUM((xi-yi)2))) as a BINARY_DOUBLE. This value is also called magnitude or size and represents the Euclidean distance between the vector and the origin. Syntax Description of the illustration vector_norm.eps Parameters expr must eval...
is the field over which the vector space is defined (i.e., the set of scalars used for scalar multiplication); denotes the absolute value if and the modulus if . Triangle inequality: These properties are pretty intuitive. As the norm is a measure of the length of a vector, it is reaso...
