In regularized linear regression with
$L_p$
norm penalties
$(||w||^p)$
, where
$p ≥ 1$
, how does increasing the value of
$p$
, especially when the model weights are relatively large (
$>1$
), affect the model's bias and variance?
In the case of
$p=1,p=2$
we get LASSO and Ridge Regression, respectively which as I understand aims to minimize overfitting by introducing bias and lowering the variance.
Does the same hold for larger values of
$p$
? What is the relationship between p and the bias-variance trade-off?.
