Label-Efficient Grasp Joint Prediction with Point-JEPA

arXiv:2509.13349v2 Announce Type: replace-cross Abstract: We study whether 3D self-supervised pretraining with Point–JEPA enables label-efficient grasp joint-angle prediction. Meshes are sampled to point clouds and tokenized; a ShapeNet-pretrained Point–JEPA encoder feeds a $K{=}5$ multi-hypothesis head trained with winner-takes-all and evaluated…

MDBench: Benchmarking Data-Driven Methods for Model Discovery

arXiv:2509.20529v1 Announce Type: new Abstract: Model discovery aims to uncover governing differential equations of dynamical systems directly from experimental data. Benchmarking such methods is essential for tracking progress and understanding trade-offs in the field. While prior efforts have focused mostly…

Learning to Bid Optimally and Efficiently in Adversarial First-price Auctions

arXiv:2007.04568v2 Announce Type: replace Abstract: First-price auctions have very recently swept the online advertising industry, replacing second-price auctions as the predominant auction mechanism on many platforms. This shift has brought forth important challenges for a bidder: how should one bid…

Generalizable Diabetes Risk Stratification via Hybrid Machine Learning Models

arXiv:2509.20565v1 Announce Type: new Abstract: Background/Purpose: Diabetes affects over 537 million people worldwide and is projected to reach 783 million by 2045. Early risk stratification can benefit from machine learning. We compare two hybrid classifiers and assess their generalizability on…

Redefining Neural Operators in $d+1$ Dimensions

arXiv:2505.11766v2 Announce Type: replace Abstract: Neural Operators have emerged as powerful tools for learning mappings between function spaces. Among them, the kernel integral operator has been widely validated on universally approximating various operators. Although many advancements following this definition have…

PIRF: Physics-Informed Reward Fine-Tuning for Diffusion Models

arXiv:2509.20570v1 Announce Type: new Abstract: Diffusion models have demonstrated strong generative capabilities across scientific domains, but often produce outputs that violate physical laws. We propose a new perspective by framing physics-informed generation as a sparse reward optimization problem, where adherence…
