New ridge regression method handles non-identical data

Researchers have developed a new statistical method for ridge regression using random features, specifically designed for high-dimensional, non-identically distributed data. This approach accounts for variance profiles in both training and test datasets, moving beyond traditional homogeneous sampling models. The derived asymptotic equivalents for training and test risks reveal how heterogeneous variance can impact generalization and potentially lead to double-descent behavior with small ridge parameters.
