What cross-validation strategies does this skill support?

It supports a wide range of strategies including K-Fold, Stratified K-Fold, Group K-Fold, and Time-Series splits.

Can I use this with deep learning frameworks?

Yes, the skill provides patterns and code snippets compatible with PyTorch and TensorFlow as well as Scikit-Learn.

Does it help with hyperparameter tuning?

Yes, it can set up nested cross-validation to ensure hyperparameter optimization doesn't lead to over-optimistic performance estimates.

How does this prevent data leakage?

The skill implements best practices for pipeline construction, ensuring preprocessing steps are fit only on training folds to prevent information from leaking into the test set.
