Five Python decorator patterns designed for production machine learning systems: automatic retry with exponential backoff for flaky external calls, input validation and schema enforcement before inference, result caching with TTL to reduce redundant computation, memory-aware execution using psutil to prevent OOM crashes, and structured execution logging for observability. Each decorator keeps core ML logic clean by pushing operational concerns to the edges, improving reliability and maintainability of inference pipelines.
