Discuss the trade-offs between diffusion models and quantization for demand forecasting.
Machine learning questions at Zscaler test both theoretical understanding and practical experience. This Take-home Project question evaluates your knowledge of ML fundamentals and your ability to apply them to real-world problems.
What the Interviewer Expects
- Explain the concept clearly with intuitive examples
- Discuss when and why to use this technique
- Identify common pitfalls and how to avoid them
- Compare with alternative approaches at a high level
Key Topics to Cover
How to Approach This
- Understand the bias-variance trade-off. High training accuracy but low test accuracy signals overfitting.
- Choose evaluation metrics carefully based on the problem. Accuracy alone is often insufficient.
- Feature engineering is often more impactful than model selection.
- Know when to use tree-based models (tabular data) vs neural networks (unstructured data).
- Handle class imbalance with SMOTE, class weights, or appropriate loss functions.
Possible Follow-up Questions
- How would you detect and handle concept drift?
- What regularization technique would you use and why?
- How would you explain this model's predictions to a non-technical stakeholder?
- What are the computational costs of this approach at scale?
