Painting galaxies into dark matter halos using machine learning
Shankar Agarwal, Romeel Davé, Bruce A. Bassett
We develop a machine learning (ML) framework to populate large dark matter-only simulations with baryonic galaxies. Our ML framework takes input halo properties including halo mass…
EDEN: Evolutionary Deep Networks for Efficient Machine Learning
Emmanuel Dufourq, Bruce A. Bassett
Deep neural networks continue to show improved performance with increasing depth, an encouraging trend that implies an explosion in the possible permutations of network architectur…
Text Compression for Sentiment Analysis via Evolutionary Algorithms
Emmanuel Dufourq, Bruce A. Bassett
Can textual data be compressed intelligently without losing accuracy in evaluating sentiment? In this study, we propose a novel evolutionary compression algorithm, PARSEC (PARts-of…
MeerKLASS: MeerKAT Large Area Synoptic Survey
Mario G. Santos, Michelle Cluver, Matt Hilton +35
We discuss the ground-breaking science that will be possible with a wide area survey, using the MeerKAT telescope, known as MeerKLASS (MeerKAT Large Area Synoptic Survey). The curr…
The MeerKAT International GHz Tiered Extragalactic Exploration (MIGHTEE) Survey
Matt J. Jarvis, A. R. Taylor, I. Agudo +54
The MIGHTEE large survey project will survey four of the most well-studied extragalactic deep fields, totalling 20 square degrees to Jy sensitivity at Giga-Hertz frequencies, as…
Automated Problem Identification: Regression vs Classification via Evolutionary Deep Networks
Emmanuel Dufourq, Bruce A. Bassett
Regression or classification? This is perhaps the most basic question faced when tackling a new supervised learning problem. We present an Evolutionary Deep Learning (EDL) algorith…
zBEAMS: A unified solution for supernova cosmology with redshift uncertainties
Ethan Roberts, Michelle Lochner, José Fonseca +3
Supernova cosmology without spectra will be an important component of future surveys such as LSST. This lack of supernova spectra results in uncertainty in the redshifts which, if…
Age-dating Luminous Red Galaxies observed with the Southern African Large Telescope
A. L. Ratsimbazafy, S. I. Loubser, S. M. Crawford +4
We measure a value for the cosmic expansion of (stat) 44(syst) km s Mpc at a redshift of based on the differential age techniq…
