The cell clustering performance of HyperG-VAE on the single-cell datasets compared with six baseline methods on four key metrics: NMI, ARI, COM, and HOM. NMI, normalized mutual information (the higher the value, the better); ARI, adjusted rand index (the higher the value, the better); COM, completeness (the higher the value, the better); HOM, homogeneity (the higher the value, the better).
