Web14 de fev. de 2024 · The L2 norm is highly sensitive to outliers since it squares the differences between the vector elements. As a result, a single outlier can significantly affect the L2 norm value. The L1 norm and L0 norm are less sensitive to outliers than the L2 norm. The L1 norm sums up the absolute values of the vector elements, which reduces … WebWe used vector norms to measure the length of a vector, and we will develop matrix norms to measure the size of a matrix. The size of a matrix is used in determining whether the solution, x, of a linear system Ax = b can be trusted, and determining the convergence rate of a vector sequence, among other things. We define a matrix norm in the same way we …
