Principal Component Regression Dominates Spectral Filters for Linear Regression

By PulseAugur Editorial · [1 sources] ·

A new paper compares the performance of various spectral filters for linear regression, including Principal Component Regression (PCR), gradient descent (GD), and ridge regression. The research demonstrates that PCR consistently outperforms other monotone spectral filters, offering a risk that is no larger by a constant factor and, in some cases, is polynomially smaller. This finding extends previous work and establishes PCR as an optimal and admissible choice among these filters. AI

IMPACT Establishes Principal Component Regression as an optimal method for linear regression tasks, potentially influencing future model development.

    Principal Component Regression Dominates all Monotone Spectral Filters for Linear Regression

    We compare the instance-wise, finite-sample risks of monotone spectral filters for linear regression, a broad class of estimators including principal component regression (PCR), gradient descent (GD), and ridge regression. We show that PCR dominates all monotone spectral filters:…
