Hard Way, The Only Way: Provable Merits of Training on Hardest Examples

The paper presents a high‑dimensional theory of learning with data pruning via weighted empirical risk minimization. It analyzes pruning along a one‑dimensional subspace and derives limiting test‑error curves as input dimension and sample size grow with a fixed ratio. The authors show that, in the high‑sample regime, the optimal strategy is to keep only the 2N hardest examples, achieving a Bayes‑optimal error scaling of order N/P instead of the usual sqrt(N/P).

Structured vs. Unstructured Pruning: An Exponential Gap

arXiv:2603. 02234v3 Announce Type: replace-cross Abstract: The Strong Lottery Ticket Hypothesis (SLTH) states that large, randomly initialized neural networks contain sparse subnetworks capable of approximating a target function at initialization without training, suggesting that pruning alone is sufficient.

Reconciling Universal and Uniform Learning with $Q$-Aggregation

The paper investigates regression with bounded responses, comparing two learning frameworks: model selection aggregation, which requires improper algorithms to achieve minimax excess risk, and universal learning, where empirical risk minimization suffices for exponential learning rates. For finite hypothesis classes, the authors show that the $Q$-aggregation estimator simultaneously attains minimax optimal tails and exponential universal rates, while other common estimators fail to do so. For countably infinite classes, they prove an inherent trade‑off between exponential universal and minimax uniform rates, resolved by combining optimal algorithms from each framework via $Q$-aggregation.
