Online learning of smooth functions on $mathbb{R}$

arXiv:2604.03525v1 Announce Type: new Abstract: We study adversarial online learning of real-valued functions on $mathbb{R}$. In each round the learner is queried at $x_tinmathbb{R}$, predicts $hat y_t$, and then observes the true value $f(x_t)$; performance is measured by cumulative $p$-loss…

Synthetic Sandbox for Training Machine Learning Engineering Agents

arXiv:2604.04872v1 Announce Type: cross Abstract: As large language model agents advance beyond software engineering (SWE) tasks toward machine learning engineering (MLE), verifying agent behavior becomes orders of magnitude more expensive: while SWE tasks can be verified via fast-executing unit tests,…

NASTaR: NovaSAR Automated Ship Target Recognition Dataset

arXiv:2512.18503v3 Announce Type: replace-cross Abstract: Synthetic Aperture Radar (SAR) offers a unique capability for all-weather, space-based maritime activity monitoring by capturing and imaging strong reflections from ships at sea. A well-defined challenge in this domain is ship type classification. Due…

Metriplector: From Field Theory to Neural Architecture

arXiv:2603.29496v2 Announce Type: replace-cross Abstract: We present Metriplector, a neural architecture primitive in which the input configures an abstract physical system — fields, sources, and operators — and the dynamics of that system is the computation. Multiple fields evolve via…

Common Inpainted Objects In-N-Out of Context

arXiv:2506.00721v2 Announce Type: replace-cross Abstract: We present Common Inpainted Objects In-N-Out of Context (COinCO), a novel dataset addressing the scarcity of out-of-context examples in existing vision datasets. By systematically replacing objects in COCO images through diffusion-based inpainting, we create 97,722…

Unlearning Noise in PINNs: A Selective Pruning Framework for PDE Inverse Problems

arXiv:2602.19967v3 Announce Type: replace Abstract: Physics-informed neural networks (PINNs) provide a promising framework for solving inverse problems governed by partial differential equations (PDEs) by integrating observational data and physical constraints in a unified optimization objective. However, the ill-posed nature of…
