Error Analysis for Solving Elliptic Interface Problems with Randomized Neural Networks

This paper presents a unified error analysis of randomized neural networks (RaNNs) for elliptic interface problems. We first derive an integral representation of Barron functions using the standard $\tanh$ activation, which yields a $C^2$-approximation bound valid for any hidden-parameter distribution supported on a cu...

ENAS-BASED YOLOv8 IMPROVEMENT WITH JOINT STRUCTURE AND LOSS SEARCH FOR CORN SEEDLING AND WEED DETECTION

Corn seedling and weed detection during the 2–5-leaf stage is essential for precision weeding, but similar morphology, field background interference, and the accuracy-efficiency trade-off limit the practical use of lightweight detectors. To address these problems, this study proposes Corn-Weed-ENAS, an improved YOLOv8-...
