Error Analysis for Solving Elliptic Interface Problems with Randomized Neural Networks
Jun Hu, Sidi Wu
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 u…
Solar, Heliospheric and Ionospheric Physics: Pathfinders, Precursors and SKAO Perspective
Pietro Zucca, Rohit Sharma, Divya Oberoi +5
The Solar, Heliospheric and Ionospheric (SHI) Physics Science Working Group of the Square Kilometre Array Observatory (SKAO) addresses the full chain of plasma processes linking th…
State-of-the-art Observation, Calibration, and Imaging Framework for Solar and Heliospheric Sciences with SKA
Divya Oberoi, Devojyoti Kansabanik, Soham Dey +6
The Sun is a surprisingly difficult radio source to observe and image, even with the SKA. It is multiple orders brighter than the typical radio sources, which sensitive radio teles…
An automated, self-calibration based pipeline for high-fidelity solar imaging with LOFAR: SIMPL
Soham Dey, Divya Oberoi, Pietro Zucca +3
The LOw Frequency ARray (LOFAR) is capable of imaging spectroscopy of the Sun in the 10-240 MHz frequency range, with high spectral, temporal, and spatial resolution. However, the…
