What is L1 L2 norm?
Calculating the size or length of a vector is often required either directly or as part of a broader vector or vector-matrix operation. The length of the vector is referred to as the vector norm or the vector’s magnitude. The length of a vector is a nonnegative number that describes the extent of the vector in space, and is sometimes referred to as the vector’s magnitude or the norm.
The L1 norm is calculated as the sum of the absolute values of the vector. The L2 norm is calculated as the square root of the sum of the squared vector values.
