Foundational
📊 Evaluation & ML Foundations
Ensembling: Bagging, Boosting, StackingEnsembles combine multiple models to beat any single one, because if their errors are decorrelated, combining cancels mistakes. Bagging trains parallel models on bootstrap samples and averages (reducing variance, e.g. random forest); boosting trains models sequentially to fix prior errors (reducing bias, e.g. XGBoost); stacking trains a meta-model to combine base models. Diversity among models is the requirement. Applied-AI interviews probe it because gradient boosting dominates tabular ML and the bias/variance framing connects to everything.
