Chapter 5: The "Exclusive" Cheat Sheet (3 Pages of Tables)
- When to use Logistic Regression vs. XGBoost vs. Two-Tower DNN.
- When to use DynamoDB vs. Cassandra vs. Redis for features.
- Real-time (Kafka) vs. Micro-batching (Flink) vs. Batch (Airflow).
Chapter 4: Scaling Inference
- Online Inference: Model as a service (GPU utilization, batching strategies).
- Batch Inference: Spark jobs, Airflow schedules.
- Edge Deployment: Quantization, pruning, TFLite vs. CoreML.
3. Airbnb: Search Ranking (Sorting)
- The catch: Two-sided marketplace (Guest AND Host satisfaction).
- The architecture: Learning to Rank (LTR) with pairwise loss.
- The "exclusive" trick: Add a "dispersion" penalty. Don't show 10 identical apartments; show variety. Use NDCG (Normalized Discounted Cumulative Gain) for evaluation.
