Question & Answer
Choose the Best Answer
They reduce overfitting by penalizing complex models.
They increase model complexity to enhance performance.
They eliminate the need for feature selection entirely.
They ensure that all parameters are non-zero.
Understanding the Answer
Let's break down why this is correct
Regularizers add a small extra cost that grows with the size of the coefficients. Other options are incorrect because The idea that making the model more complex helps it learn better is a common mistake; Some people think that regularizers replace the need to pick which features to use.

Definition
Regularizers are functions that control the sensitivity of predictive models by penalizing complex or sensitive parameter configurations. Common regularizers include `2 (ridge) and `1 (Lasso) regularization, which encourage stable and sparse parameter solutions.
