This repository's encoders at stage 2 and later were trained by distillation from H-optimus-0 (Bioptimus), which is

H-optimus-0 itself is not redistributed here. Our encoders are new weights (a ViT-S/16, 22M parameters) trained to match
its outputs on TCGA tiles.

Training and evaluation data: The Cancer Genome Atlas (NCI Genomic Data Commons, open access); CPTAC-BRCA (open);
Yale-HER2 (The Cancer Imaging Archive, HER2-TUMOR-ROIS, CC BY 4.0). HEROHE (CC BY-NC-ND 3.0) and BCNB (non-commercial)
were used for evaluation only, and no per-slide data from them are included.
