Highly Adaptive Ridge regression method introduced for tabular data

A new regression method called Highly Adaptive Ridge (HAR) has been proposed, achieving a dimension-free convergence rate of n^{-1/3} for right-continuous functions with square-integrable sectional derivatives. This method is particularly suited for tabular data and is computationally efficient, functioning as kernel ridge regression with a specific data-adaptive kernel. The research also establishes connections between HAR and kernel ridge regression in Sobolev spaces and validates the theory through simulations and real-world data. AI
