The effects of image augmentations when training machine learning models in astronomy
Leon H. Butterworth, Ashley Spindler
We measure the influence of image augmentations and training dataset size when training a deep neural network to classify galaxy morphology. Data augmentation is an integral step w…
AstroVaDEr: Astronomical Variational Deep Embedder for Unsupervised Morphological Classification of Galaxies and Synthetic Image Generation
Ashley Spindler, James E. Geach, Michael J. Smith
We present AstroVaDEr, a variational autoencoder designed to perform unsupervised clustering and synthetic image generation using astronomical imaging catalogues. The model is a co…
