Artificial Intelligence Engineer Interview Questions and Answers
"Can you explain the difference between supervised and unsupervised learning?"
This question assesses your foundational knowledge of machine learning paradigms. It's crucial to demonstrate your understanding of different learning techniques and their applications.
How to Answer It
Clearly define supervised and unsupervised learning, highlighting key differences. Provide examples of when each method is used and discuss any relevant experiences you have with both techniques.
Example Answer
"Supervised learning involves training a model on labeled data, where the input-output pairs are known. It's used for tasks like classification and regression. For example, predicting house prices based on features like size and location. Unsupervised learning, on the other hand, deals with unlabeled data and is used for clustering and association tasks. An example would be customer segmentation in marketing. In my previous role, I used supervised learning to develop a fraud detection system and unsupervised learning for customer segmentation."
"How do you handle missing or incomplete data in a dataset?"
This question evaluates your data preprocessing skills, which are critical for building reliable AI models. It reveals your approach to ensuring data quality and integrity.
How to Answer It
Discuss various techniques for handling missing data, such as imputation, deletion, or using algorithms that support missing values. Provide examples of how you've applied these methods in past projects.
Example Answer
"I handle missing data by first analyzing the extent and pattern of the missingness. For small amounts of missing data, I use imputation techniques like mean or median substitution. For larger gaps, I might use more sophisticated methods like k-nearest neighbors imputation or even model-based imputation. In one project, I used multiple imputation to handle missing values in a healthcare dataset, which significantly improved the model's accuracy."
"Can you describe a time when you had to optimize a machine learning model?"
