SARABANDE: 3/4 Point Correlation Functions with Fast Fourier Transforms
James Sunseri, Zachary Slepian, Stephen Portillo +3
We present a new package SARABANDE for measuring 3 & 4 Point Correlation Functions (3/4 PCFs) in time using Fast Fourier T…
Classification of Magnetohydrodynamic Simulations using Wavelet Scattering Transforms
Andrew K. Saydjari, Stephen K. N. Portillo, Zachary Slepian +3
The complex interplay of magnetohydrodynamics, gravity, and supersonic turbulence in the interstellar medium (ISM) introduces non-Gaussian structure that can complicate comparison…
The Catalogue for Astrophysical Turbulence Simulations (CATS)
B. Burkhart, S. Appel, S. Bialy +18
Turbulence is a key process in many fields of astrophysics. Advances in numerical simulations of fluids over the last several decades have revolutionized our understanding of turbu…
Sampling for Deep Learning Model Diagnosis (Technical Report)
Parmita Mehta, Stephen Portillo, Magdalena Balazinska +1
Deep learning (DL) models have achieved paradigm-changing performance in many fields with high dimensional data, such as images, audio, and text. However, the black-box nature of d…
Dimensionality Reduction of SDSS Spectra with Variational Autoencoders
Stephen K. N. Portillo, John K. Parejko, Jorge R. Vergara +1
High resolution galaxy spectra contain much information about galactic physics, but the high dimensionality of these spectra makes it difficult to fully utilize the information the…
Multiband Probabilistic Cataloging: A Joint Fitting Approach to Point Source Detection and Deblending
Richard M. Feder, Stephen K. N. Portillo, Tansu Daylan +1
Probabilistic cataloging (PCAT) outperforms traditional cataloging methods on single-band optical data in crowded fields (Portillo et al. 2017). We extend our work to multiple band…
