This question is not related to any specific datasets but it is a generalized one.
How often do data scientists or data analysts come across regularizations (L1 or L2) in dealing with datasets ? I know overfitting is a common scenario in building a model. So, is regularization the only way to solve this overfitting ?
Can anyone show regularizaion techniques they followed in any of the datasets of AnalyticsVidhya comepetitions ?
Thanks in advance.
