Spot Hidden Data Drift When Individual Features Seem Stable

Your features look stable, but your model is quietly failing. That's the problem this post tackles head-on.

Adversarial validation with scikit-learn can catch those subtle shifts before they undermine performance. It's a smart, practical technique for anyone who suspects their model is degrading but can't find the cause.
