A. Algorithm selection

B. Adaptive sampling

C. Feature selection

D. Hyperparameter tuning

Correct Answer: B

Question 2

Which TWO statements are true about published conda environments?

Question 4

You have built a machine model to predict whether a bank customer is going to default on a loan. You want to use Local Interpretable Model-Agnostic Explanations (LIME) to understand a specific prediction. What is the key idea behind LIME?

A. Global and local behaviors of machine learning models are similar.

B. Global behavior of a machine learning model may be complex, while the local behavior may be approximated with a simpler surrogate model.

C. Local explanation techniques are model agnostic, while global explanation techniques are not.

D. Model-agnostic techniques are more interpretable than techniques that are dependent on the types of models.
