    High-dimensional ridgeless least squares interpolation under spiked covariance structures

    Zhijun Liu, Dandan Jiang

    math.ST · cs.LG · stat.ML

    This paper investigates the asymptotic behavior of the out-of-sample prediction risk of the high-dimensional ridgeless least-squares estimator when the feature dimension $p$ and the sample size $n$ grow proportionally. We consider a generalized spiked population covariance model with multiple latent factors, where the number of spiked eigenvalues may remain finite or increase with $n$, and the spiked eigenvalues may be bounded or diverge at...
