When Foundation Models Meet Astronomical Data

Abstract
The last decade has seen major advances in artificial intelligence, with breakthrough results in many application areas. A new paradigm shift is currently occurring in AI with the rise of Foundation Models. Our work evaluates the performance of existing visual foundation models, including ViT, CLIP and DINOv2, for astronomical tasks. We adopt a common methodology based on fine-tuning and report results on GalaxyZoo datasets for classification tasks.
