Solving 3D Magnetohydrostatics with RBF-FD: Applications to the Solar Corona
Nathaniel H. Mathews, Natasha Flyer, Sarah E. Gibson
We present a novel magnetohydrostatic numerical model that solves directly for the force-balanced magnetic field in the solar corona. This model is constructed with Radial Basis Fu…
Convolutional Neural Networks and Stokes Response Functions
Rebecca Centeno, Natasha Flyer, Lipi Mukherjee +4
In this work, we study the information content learned by a convolutional neural network (CNN) when trained to carry out the inverse mapping between a database of synthetic Ca II i…
Decreasing False Alarm Rates in ML-based Solar Flare Prediction using SDO/HMI Data
Varad Deshmukh, Natasha Flyer, Kiera Van Der Sande +1
A hybrid two-stage machine learning architecture that addresses the problem of excessive false positives (false alarms) in solar flare prediction systems is investigated. The first…
Fast high-dimensional node generation with variable density
O. Vlasiuk, T. Michaels, N. Flyer +1
We present an algorithm for producing discrete distributions with a prescribed nearest-neighbor distance function. Our approach is a combination of quasi-Monte Carlo (Q-MC) methods…
ROAM: a Radial-basis-function Optimization Approximation Method for diagnosing the three-dimensional coronal magnetic field
K. Dalmasse, D. W. Nychka, S. E. Gibson +2
The Coronal Multichannel Polarimeter (CoMP) routinely performs coronal polarimetric measurements using the Fe XIII 10747 and 10798 lines, which are sensitive to the coronal…
An RBF-FD polynomial method based on polyharmonic splines for the Navier-Stokes equations: Comparisons on different node layouts
Gregory A. Barnett, Natasha Flyer, Louis J. Wicker
Polyharmonic spline (PHS) radial basis functions (RBFs) are used together with polynomials to create local RBF-finite-difference (RBF-FD) weights on different node layouts for spat…
