I know two types: l1 and l2. Don’t know the difference but seen using l2 is better.

Which kind of regularization is this?

One more question, regularization is used in machine learning only, in deep learning and neural nets it is not used?

Here is a nice article you can read about it.

(found via an internet search).

Regularization can be used in any supervised learning method.
