Interviewer

Welcome to your interview.

The question is on your right: Regularization to Reduce Overfitting. Take a moment with it first.

Problem

Scenario

You are training a supervised learning model and notice that training performance is much better than validation performance. You want the model to generalize better to unseen data.

Question

How would you regularize a model to reduce overfitting?
