Smith42/astroPT_v2.0

astroPT: a Large Observation Model for Astronomy

Here we have the model files for the astroPT project, the code to run inference with these models is found here: https://github.com/smith42/astropt

You will find the fully trained models (pretrained on 8.6 million galaxies) in folders labelled with the model parameter count in the astropt directory.

Unlike the older models which were trained on the "image" column in smith42/galaxies, these models are trained on the "cropped" galaxies from the "image_crop" column. Those galaxies have been cropped and zoomed so that they take up the majority of each image before uploading.

We get some promising scaling on this new dataset, see below:
