Opportunities and realistic risks

Who is this topic relevant for?

In simple terms, norm L1 measures the sum of the absolute values of the coefficients of a vector. Unlike the Euclidean norm, which measures the length of a vector using the square root of the sum of the squares of its components, the L1 norm calculates the sum of the absolute values of each component. This makes it a useful measure for identifying the contribution of each component to the overall magnitude. The formula for L1 norm is:

What is norm L1?

Norm L1 is used to solve linear equations and systems. It helps identify the coefficients that contribute the most to the solution. In machine learning, L1 regularization is used to select coefficients with the smallest absolute values, which often leads to better model interpretability and performance.

For example, if we have a vector [3, -4, 5], the L1 norm would be 3 + 4 + 5 = 12.
