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
