All coefficients are shrunk by the same factor i.e none are eliminated. L2 regularization will not result in sparse models.

Suppose that for a known matrix and vector , we wish to find a vector such that The standard approach is ordinary least squares linear regression. However, if no satisfies the equation or more than one does—that is, the solution is not unique—the problem is said to be ill posed. In such cases, ordinary least squares estimation leads to an overdetermined, or more often an underdetermined system of equations.
