Stop User Leakage: Group Splits

Prevent user leakage with group-aware splits—why GroupKFold matters for honest validation.
Learn how to set up group-aware splits to ensure generalization (no memorization), quantify overlap_drop, and compare grouped baselines so your metrics match production.
Tools: scikit-learn (GroupKFold, GroupShuffleSplit, cross_validate, DummyClassifier) — run the quick diagnostic before training.
Subscribe for concise AI foundations in Python and practical validation best practices.
