Galaxies can be described by features of their optical spectra such as oxygen emission lines, or morphological features such as spiral arms. Although spectroscopy provides a rich description of the physical processes that govern galaxy evolution, spectroscopic data are observationally expensive to obtain. We are able to robustly predict and reconstruct galaxy spectra directly from broad-band imaging. We present a powerful new approach using a hybrid convolutional neural network with…

Machine learning techniques to separate the cosmic from the telluric

In the Roman era, wide-field, deep, visible-to-near infrared images will revolutionize our understanding of galaxy evolution (e.g. environments, morphologies, masses, colors). The legacy value of

Rotation-invariant convolutional neural networks for galaxy morphology prediction

TLDR
A deep neural network model for galaxy morphology classification which exploits translational and rotational symmetry is developed in the context of the Galaxy Challenge, an international competition to build the best model for morphology classification based on annotated images from the Galaxy Zoo project.

Connecting optical morphology, environment, and HI mass fraction for low-redshift galaxies using deep learning

A galaxy’s morphological features encode details about its gas content, star formation history, and feedback processes, which play important roles in regulating its growth and evolution. We use deep

Using convolutional neural networks to predict galaxy metallicity from three-colour images

We train a deep residual convolutional neural network (CNN) to predict the gas-phase metallicity ($Z$) of galaxies derived from spectroscopic information ($Z \equiv 12 + \log(\rm O/H)$) using only

Dimensionality Reduction of SDSS Spectra with Variational Autoencoders

TLDR
It is found that a VAE can reconstruct the SDSS spectra well with only six latent parameters, outperforming PCA with the same number of components, and enables the fast exploration of large astronomical data sets.

Understanding Galaxy Evolution Through Emission Lines

We review the use of emission lines for understanding galaxy evolution, focusing on excitation source, metallicity, ionization parameter, ISM pressure, and electron density. We discuss the physics,

On the Variance of the Adaptive Learning Rate and Beyond

TLDR
This work identifies a problem of the adaptive learning rate, suggests warmup works as a variance reduction technique, and proposes RAdam, a new variant of Adam, by introducing a term to rectify the variance of theadaptive learning rate.

Lookahead Optimizer: k steps forward, 1 step back

TLDR
Lookahead improves the learning stability and lowers the variance of its inner optimizer with negligible computation and memory cost, and can significantly improve the performance of SGD and Adam, even with their default hyperparameter settings.
