A new research paper published on arXiv explores the learning curves and benign overfitting phenomena in spectral algorithms within large-dimensional settings. The study characterizes the excess risk across different regularization paths, identifying three distinct regimes: over-regularized, under-regularized, and interpolation. Benign overfitting is shown to occur in the latter two regimes under specific conditions related to the smoothness of the regression function. AI
