Deep Learning with C++
By :
This chapter treated a deployed model as a system under continuous observation. We began by showing how production models drift as the environment changes and how to detect that drift with lightweight, always-on summaries and stable statistical tests. You learned how to distinguish feature drift, prediction drift, prior shift, and concept drift, as well as how to use cohort-based monitoring to separate localized failures from broad system changes.
We then turned to debugging in production. Structured logs, metrics, and traces provide the evidence needed to observe regressions, reproduce failures, and isolate their causes. With fixed seeds, reproducible inputs, and targeted checks for numerical instability, data contract violations, and concurrency bugs, debugging becomes a disciplined process rather than guesswork.
Finally, we focused on retraining as an operational decision. Retraining should be triggered by evidence, implemented through reproducible pipelines, evaluated...
