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

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.

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.
