Question
Which of the following about Ridge Regularization is TRUE?1 pointIt enforces the coefficients to be lower, but not 0It minimizes irrelevant features It penalizes the size magnitude of the regression coefficients by adding a squared term All of the above
Solution
All of the above.
Ridge Regularization, also known as Ridge Regression or L2 regularization, does indeed enforce the coefficients to be lower but not necessarily zero. This is because it adds a penalty equivalent to square of the magnitude of coefficients to the loss function.
It also helps in minimizing the impact of irrelevant features. While it doesn't completely eliminate the coefficients of these features (like Lasso Regularization), it does significantly reduce their impact by shrinking their coefficients.
Lastly, as mentioned, Ridge Regularization penalizes the size or magnitude of the regression coefficients by adding a squared term to the loss function. This penalty term encourages simpler models that have smaller coefficient values.
