Discuss the trade-offs between few-shot learning and model pruning for demand forecasting.
This ML question from Anduril's Technical Screen goes beyond textbook definitions. The interviewer wants to see how you reason about model selection, evaluation metrics, and the practical challenges of deploying ML in production.
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
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 ensure reproducibility in your ML pipeline?
- How would you explain this model's predictions to a non-technical stakeholder?
- When would you prefer a simpler model over a complex one?

Core Concept: Contrastive Learning vs Batch Normalization
Contrastive learning is a self-supervised learning approach that focuses on learning representations by comparing positive pairs (similar items) and negative pairs (dissimilar items). The core idea is...
How It Works: Mechanisms of Contrastive Learning and Batch Normalization
Contrastive learning works by leveraging data augmentation to create multiple views of the same instance, which are then used to form positive pairs. The model learns to map these views closer in the ...
