Artificial Intelligence Projects and Problem Solving Questions

Detailed discussion of artificial intelligence and machine learning projects you have designed, implemented, or contributed to. Candidates should explain the problem definition and success criteria, data collection and preprocessing, feature engineering, model selection and justification, training and validation methodology, evaluation metrics and baselines, hyperparameter tuning and experiments, deployment and monitoring considerations, scalability and performance trade offs, and ethical and data privacy concerns. If practical projects are limited, rigorous coursework or replicable experiments may be discussed instead. Interviewers will assess your problem solving process, ability to measure success, and what you learned from experiments and failures.

Design a monitoring plan for a production binary classifier. List the model, data, and business metrics you would track, how you would detect anomalies in these metrics, recommended alert thresholds or patterns, and automated remediation steps or playbooks you might implement. Also suggest dashboard views useful for stakeholders.

Explain how to design and run ablation studies to identify which features or model components drive performance. Provide an example plan for systematically removing or replacing components, how to control for variance, and how to assess statistical significance of observed changes.

Write a Python function (without using external libraries) that computes ROC AUC and PR AUC given arrays of true binary labels and predicted scores. Include handling for edge cases such as all-positive or all-negative labels and explain the time complexity of your implementation.

Describe a reproducible ML experiment workflow you would build for a team. Cover code and environment versioning, dataset and artifact tracking, experiment logging (hyperparameters and metrics), containerization, and how auditors can rerun experiments to validate results.

Design an active learning loop to label rare fraud events. Describe selection strategies (uncertainty sampling, query-by-committee, density-weighted), how you would batch queries for labelers, quality control for labelers, and stopping criteria for the active loop.
