Favorita: XGBoost Train & Predict
A focused XGBoost pipeline for forecasting Favorita grocery sales — feature engineering, training with cross-validation, and prediction. The fast, interpretable baseline every forecasting project should start with.
Primary Outcome
A trained, validated XGBoost forecasting model and a reusable predict step with feature importances.
Solution
A tuned XGBoost pipeline with proper feature engineering and time-series cross-validation that delivers an accurate, interpretable forecasting baseline in days.
Deliverables
A feature-engineering step (lags, rolling windows, calendar and promotion features)
A training script with time-aware cross-validation and tuned hyperparameters
Evaluation against a strong baseline, reported by store and item family
A predict step that outputs forecasts plus feature importances
Saved model artifacts ready to hand to MLflow or Vertex
Strategic Context
Teams reach for neural networks far too early. For most retail and operations forecasting, a well-engineered XGBoost model is faster, cheaper, more interpretable, and roughly as accurate. The hard part was never the algorithm — it's the features and the validation. This template gets both right.
Technical Architecture

Problem Statement
Forecasting projects stall on over-engineering — teams chase deep learning before they have a baseline, and skip the time-aware validation that keeps a model honest.

What's Included
Python scripts for feature engineering, model training with cross-validation, evaluation, and batch prediction, plus the saved model artifacts and a requirements file.
FAQs
Why XGBoost over a neural net?
For tabular, store-item forecasting it's faster, cheaper, more interpretable, and usually just as accurate. Earn your way to deep learning.
Can I track these runs?
Yes — the artifacts drop straight into the MLflow Tracking template.
