Scoring millions of candidate ads in 40ms is impossible. Break the system into two stages:
: Mention near-line processing for dynamic streaming updates. 7. Monitoring, Evaluation, and Iteration An ML system is never truly finished after deployment:
Creative text tokens, advertiser ID, historical aggregate CTR, campaign budget. Offline/Online Feature Store / Batch Ingestion.
The Ultimate Guide to Cracking the Machine Learning System Design Interview
User historical click rates (computed over rolling 1-hour, 1-day, and 7-day windows), ad historical popularity, and contextual matching (user query vs. ad keywords).
Context Features: Time of day, device type, current location.
Transition to advanced architectures. Explain why you chose a specific model. For instance, choose a Two-Tower Neural Network for scalable recommendation retrieval, or a Gradient Boosted Decision Tree (GBDT) for tabular fraud data.
Learning to Rank (LTR) and Embedding-based retrieval.
