Advanced Cross-Validation for Sequential Data: A Guide to Avoiding Data Leakage
Improve generalization capabilities while keeping data in order
Cross-validation (CV) is a statistical technique to evaluate generalization capabilities of a machine learning model.
Standard K-Fold fails on sequential data.
To avoid data leakage, we need to:
- Maintain temporal orders,
- Use time-series specific validation methods, and
- Prevent autocorrelation between training and validation datasets.
This technical deep dive explores specialized validation strategies—including Walk-Forward, Gap, and hv-Blocked CV—with a performance simulation comparing PyTorch GRU and Scikit-Learn SVR models.
