Research Type Theoretical We study the cost of overfitting in noisy kernel ridge regression (KRR)... We analyze the cost of overfitting under a Gaussian universality ansatz using recently derived (non-rigorous) risk estimates in terms of the task eigenstructure. Our analysis provides a more refined characterization of benign, tempered and catastrophic overfitting (cf. Mallinar et al., 2022).For the rest of this paper, we will simply treat it as an equivalence, formally proving facts about the omniscient risk estimate R( ˆfδ). Thus, our results follow by analyzing the expression from (6).
