Feedback Loop

• Q: How to serve a large deep model under 50 ms p95? A: Use model distillation/quantization, serve on GPU inference server with batching, use caching for repeated requests, colocate feature store, and autoscale.
• Q: How detect model drift? A: Monitor input distribution (KS test), monitor prediction distribution and key metrics; trigger retrain on threshold breaches and use shadow traffic to validate.
• Q: CI for models? A: Automated data checks, unit tests, training reproducibility checks, evaluation against baseline, canary deployments and metrics-based promotion.
