Time series forecasting uses machine learning to predict future values by modeling temporal dependencies and patterns. This Skill implements modern approaches including tree-based methods like LightGBM, deep learning with Transformers, and specialized models like Chronos, combined with lag and rolling feature engineering to capture sequential relationships.

Temporal validation prevents data leakage by respecting chronological order during model testing. This Skill applies backtesting and multi-step forecasting strategies that evaluate predictions on future unseen periods, ensuring your model generalizes rather than overfitting to historical patterns.

Yes. This Skill covers both tree-based methods (LightGBM) and deep learning (Transformers, RNNs) for time series, enabling you to compare approaches, select the best model for your data, and apply cross-method evaluation to determine which handles your temporal dependencies most effectively.

Explainability uses SHAP to interpret feature importance and model decisions. Production readiness requires drift monitoring to detect when model performance degrades over time, combined with robust validation, proper feature engineering, and end-to-end pipelines that track model behavior in live deployments.

Lag features capture recent historical values; rolling window features capture trends and seasonality over time. This Skill demonstrates how to construct and validate these engineered features alongside advanced models to handle long-term dependencies and improve forecast accuracy.

Yes. This Skill includes Future-Guided Learning patterns for event prediction alongside standard point forecasting. It addresses scenarios where you need to detect or predict specific events within temporal sequences, not just predict continuous future values.
