Your question is L1 vs L2 Regularization. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
What is the difference between Lasso (L1) and Ridge (L2) regularization?
Asked in the Technical / Machine Learning Round stage. ML theory and regularization questions.
Give a practical comparison suitable for choosing a regularizer in a production linear or generalized linear model. Explain the objective functions, effect on coefficients, behavior with correlated and irrelevant features, optimization implications, and how you would select the regularization strength. Discuss how the choice affects offline evaluation, serving cost, feature drift, and training-serving consistency.
