EMber: Learning the Shared Latent Structure of Cryo-EM Inverse Problems

EMber is a family of pretrained vision transformers for extracting representations from single-particle cryo-EM particle images. Given a particle image, EMber produces an image-level embedding and spatial patch features for use in downstream analysis. The models were trained using self-distillation on over 50 million experimental particle images from 214 EMPIAR datasets, together with simulated projections from 268,000 molecular assemblies.

EMber-Small has 21.4M parameters and uses a 16x16 patch size.
