How to Answer

Discuss the definitions of both supervised and unsupervised learning, providing examples of each. Highlight the types of problems each approach is best suited for.

Example

“Supervised learning involves training a model on labeled data, where the outcome is known, such as predicting house prices based on features like size and location. In contrast, unsupervised learning deals with unlabeled data, aiming to find hidden patterns, like customer segmentation in marketing data.”

2. What are some common metrics used to evaluate the performance of a machine learning model?

This question tests your knowledge of model evaluation techniques.

How to Answer

Mention metrics such as accuracy, precision, recall, F1 score, and ROC-AUC, and explain when to use each.

Example

“Common metrics include accuracy for overall correctness, precision for the quality of positive predictions, and recall for the ability to find all relevant instances. The F1 score is useful when you need a balance between precision and recall, especially in imbalanced datasets.”

3. Describe a project where you implemented a machine learning algorithm. What challenges did you face?

This question allows you to showcase your practical experience.

How to Answer

Detail the project, the algorithm used, and the challenges encountered, along with how you overcame them.

Example
