A new paper introduces a theoretical framework for model selection using cross-validation, particularly when domain knowledge is incorporated. The research establishes deviation bounds based on VC dimension for the entire learning pipeline, extending existing results for unbounded loss functions. It proposes 'Learning Spaces' to structure candidate models based on domain knowledge, demonstrating that well-adapted Learning Spaces can significantly outperform standard methods like OLS, LASSO, and ridge regression in high-dimensional linear regression.
