AstroClassification and Redshifts Pretraining Dataset
This dataset was used in the masked autoencoding pretraining step for the AstroClassification and Redshifts tasks introduced in Connect Later: Improving Fine-tuning for Robustness with Targeted Augmentations. This is a dataset of simulated astronomical time-series (e.g., supernovae, active galactic nuclei), and the task is to classify the object type (AstroClassification) or predict the object's redshift (Redshifts).
