Spherinator

Spherinator and HiPSter are tools that provide explorative access and visualization for multimodal data from extremely large astrophysical datasets, ranging from exascale cosmological simulations to multi-billion object observational galaxy surveys.

A variational autoencoder (VAE) will be trained using PyTorch Lightning to compress the structural data into a low-dimensional spherical latent space.
