Comparing regularisation paths of (conjugate) gradient estimators in ridge regression
NeutralArtificial Intelligence
This article explores the performance of various iterative algorithms, including standard gradient descent, gradient flow, and conjugate gradients, in minimizing a penalized ridge criterion in linear regression. It highlights the fast numerical convergence of conjugate gradients while addressing the complexities in assessing their statistical properties due to non-linearities. Understanding these methods is crucial for improving regression analysis and optimizing model performance, making this research relevant for statisticians and data scientists.
