Mathematically, we can see that both the L1 and **L2 norms** are measures of the magnitude of the weights: the sum of the absolute values in the case of the L1 **norm**, and the sum of **squared** values for the **L2 norm**. So larger weights give a larger **norm**. This means that, simply put, minimizing the **norm** encourages the weights to be small, which in turns.

This model solves a regression model where the loss function is the linear least **squares** function and regularization is given by the **l2**-**norm**. Also known as Ridge Regression or Tikhonov regularization. This estimator has built-in support for multi-variate regression (i.e., when y is a 2d-array of shape (n_samples, n_targets)). <b>Ridge</b> <b>regression</b> model selection with. Specifically talking about Ridge Regression's cost function since Ridge Regression is based off of the **l 2 norm**. We should expect the cost function to be: J ( θ) = M S E ( θ) + α ∑ i = 1 n θ i 2. Actual: J ( θ) = M S E ( θ) + α 1 2 ∑ i = 1 n θ i 2. regression regularization tikhonov-regularization. Share. Improve this question.

1. L1 Regularization. 2. **L2** Regularization. A regression model that uses L1 regularization technique is called Lasso Regression and model which uses **L2** is called Ridge Regression. The key difference between these two is the penalty term. Ridge regression adds " **squared** magnitude " of coefficient as penalty term to the loss function.
