How do I approach Machine Learning interview questions?

Machine Learning questions require understanding of core concepts and practice. PracHub provides solutions with explanations to help you master machine learning interviews.

What difficulty level is this interview question?

This is a easy difficulty Machine Learning question, commonly asked during Technical Screen rounds at Amazon.

What role is this question designed for?

This question is commonly asked for Machine Learning Engineer candidates at Amazon during technical interviews.

Describe overfitting and L1/L2 regularization

Q: Describe overfitting and L1/L2 regularization

This question evaluates understanding of model generalization and regularization techniques by probing knowledge of overfitting and L1/L2 regularization and their effects on model parameters.

Define overfitting in machine learning and explain why it is harmful.

Then describe L1 and L2 regularization:

How each one modifies the loss function.
The qualitative effect of each (e.g., sparsity, weight shrinkage).
How they help mitigate overfitting and when you might prefer one over the other.
