Question

After applying a regularization penalty in linear regression, you find that some of the coefficients of $w$ are zeroed out. Which of the following penalties might have been used?

(a) L0 norm

(b) L1 norm

(c) L2 norm

(d) either (A) or (B)

(e) any of the above

Answer 1

I think Option B i.e L1 norm has been used bcz after using L1 norm some of the coefficients get exactly zero.

Comments

if you understand the questions clearly, the regularization term in both L1 and L2 will make the value of $w$ zeroed out. so asnwer will be D
