Comparing regularisation paths of (conjugate) gradient estimators in ridge regression
Laura Hucker, Markus ReiÃ, Thomas Stark
We consider standard gradient descent, gradient flow and conjugate gradients as iterative algorithms for minimising a penalised ridge criterion in linear regression. While it is we…

Implicit vs. explicit regularization for high-dimensional gradient descent
Thomas Stark, Lukas Steinberger
In this paper we investigate the generalization error of gradient descent (GD) applied to an -regularized OLS objective function in the linear model. Based on our analysis…
