Establish automated pipelines to trigger model retraining when drift metrics (like Population Stability Index) cross a specific threshold. Utilizing GitHub and Community Resources Effectively
: Focuses heavily on query understanding, semantic search via vector embeddings, and ranking algorithms that balance relevance with business logic (e.g., pricing, availability). Ad Click-Through Rate (CTR) Prediction
If your deep learning model is too slow for online serving, propose optimizations like model quantization, pruning, or splitting the system into a fast Retrieval (candidate generation) phase followed by a precise Ranking phase. machine learning system design interview alex xu pdf github

: Usually structured as a two-stage pipeline: Retrieval (filtering millions of items down to hundreds using fast approximate nearest neighbors like FAISS) and Ranking (using a heavy deep learning model to precisely score the top candidates). Search and Information Retrieval (e.g., Google, Airbnb)
