Basic Inequalities for First-Order Optimization with Applications to Statistical Risk Analysis

The paper proposes a set of elementary inequalities as a general tool for analyzing first-order iterative optimization methods, aiming to unify how implicit and explicit regularization are understood. Building on existing comparison inequalities, the authors show how this framework can be used to study statistical risk. It is a revised cross-list submission to arXiv's machine learning category.

Functional SVD Framework Proposed for Regularized Multivariate Functional PCA

A new arXiv paper presents a framework for regularized multivariate functional principal component analysis built on a functional singular value decomposition. The approach generalizes existing MFPCA methods by adding dual penalization, which regularizes the decomposition in two ways. The work targets dimension reduction and analysis of multivariate functional data.

One-shot pruning found to act as implicit regularizer for speech recognition models

A study argues that one-shot magnitude pruning does more than compress neural networks, acting as an implicit regularizer for automatic speech recognition. Testing with Whisper-small, the authors combine gradient- and Fisher-based sensitivity measures to guide which weights to remove. The work reframes pruning as a training technique rather than only a efficiency tool.

Study Examines Regularization Effects in Linear Recommendation Models

A new arXiv preprint analyzes how regularization shapes the behavior of linear recommendation models. The work situates these simpler models against deep-learning-inspired recommenders that currently lead on standard recommendation benchmarks. It appears aimed at clarifying when and why regularization choices matter for ranking performance.

arXiv Paper Introduces High-Order Regularization for Federated Learning

A new arXiv preprint addresses a problem in federated learning where clients that run multiple local optimization steps produce parameter updates of very different scales. The authors observe that the proximal term used by FedProx exerts a restraining force that scales only linearly with update size, giving it weak leverage over large displacements, and they propose a higher-order regularization scheme as a stronger alternative.

Bayes-Optimal Diagonal Regularization in Modal Inverse Problems Follows Closed-Form Power Law

A new machine learning theory paper establishes a 'diagonal saturation principle' for modal inverse problems. When truncation noise is isotropic, the optimal diagonal Tikhonov regularizer takes a closed-form power-law shape whose exponent is fixed entirely by the prior. The authors argue this explains why learned regularization converges on an analytic solution rather than a data-dependent one.
