Design an end-to-end ML system for demand forecasting, covering data collection, feature engineering, model selection, training, and serving.

Machine learning questions at Cruise test both theoretical understanding and practical experience. This Onsite question evaluates your knowledge of ML fundamentals and your ability to apply them to real-world problems.

What the Interviewer Expects
  • Explain the mathematical foundations with clarity
  • Discuss practical implementation considerations and hyperparameter tuning
  • Analyze the technique's strengths and weaknesses for different data types
  • Demonstrate understanding of evaluation methodology and metrics
  • Connect theory to real-world applications with concrete examples
Key Topics to Cover
Class imbalance handling
Model interpretability and explainability
Regularization techniques (L1, L2, dropout)
Bias-variance trade-off
Cross-validation and model evaluation
How to Approach This
  1. Understand the bias-variance trade-off. High training accuracy but low test accuracy signals overfitting.
  2. Choose evaluation metrics carefully based on the problem. Accuracy alone is often insufficient.
  3. Feature engineering is often more impactful than model selection.
  4. Know when to use tree-based models (tabular data) vs neural networks (unstructured data).
  5. Handle class imbalance with SMOTE, class weights, or appropriate loss functions.
Possible Follow-up Questions
  • When would you prefer a simpler model over a complex one?
  • What regularization technique would you use and why?
  • How would you detect and handle concept drift?
  • How would you ensure reproducibility in your ML pipeline?

Core Concept: Demand Forecasting in ML

Demand forecasting in machine learning involves predicting future demand for a service or product based on historical data. The core concept revolves around time series forecasting, regression analysi...

How It Works: Mathematical Mechanisms

For demand forecasting, we could use a regression model, such as a linear regression or more complex methods like Gradient Boosting Machines (GBM). In this context, the model predicts demand (Y) as a ...
