Publisher summary· verbatim

arXiv:2605.28679v1 Announce Type: new Abstract: We consider $L^2$-regularized linear (ridge) regression over a finite data sample $X$ with bounded covariance and linear prediction targets $y$ with additive isotropic noise of finite variance. We present an iterative procedure to compute the optimal r
