Lessons Learned from the Two Largest Galaxy Morphological Classification Catalogues built by Convolutional Neural Networks

Ting-Yun Cheng, H. Domínguez Sánchez, J. Vega-Ferrero +54

We compare the two largest galaxy morphology catalogues, which separate early and late type galaxies at intermediate redshift. The two catalogues were built by applying supervised…

Harvesting the Lyα forest with convolutional neural networks

Ting-Yun Cheng, Ryan Cooke, Gwen Rudie

We develop a machine learning based algorithm using a convolutional neural network (CNN) to identify low HI column density Ly absorption systems ($\log{N_{\mathrm{HI}}}/{\rm cm}…

Beyond the Hubble Sequence -- Exploring Galaxy Morphology with Unsupervised Machine Learning

Ting-Yun Cheng, Marc Huertas-Company, Christopher J. Conselice +3

We explore unsupervised machine learning for galaxy morphology analyses using a combination of feature extraction with a vector-quantised variational autoencoder (VQ-VAE) and hiera…

Galaxy Merger Rates up to z 3 using a Bayesian Deep Learning Model A Major-Merger classifier using IllustrisTNG Simulation data

Leonardo Ferreira, Christopher J. Conselice, Kenneth Duncan +3

Merging is potentially the dominate process in galaxy formation, yet there is still debate about its history over cosmic time. To address this we classify major mergers and measure…

Identifying Strong Lenses with Unsupervised Machine Learning using Convolutional Autoencoder

Ting-Yun Cheng, Nan Li, Christopher J. Conselice +3

In this paper we develop a new unsupervised machine learning technique comprised of a feature extractor, a convolutional autoencoder (CAE), and a clustering algorithm consisting of…
