# gtda.homology: Persistent homology¶

The module gtda.homology implements transformers to generate persistence diagrams.

 homology.VietorisRipsPersistence([metric, …]) Persistence diagrams resulting from Vietoris–Rips filtrations. homology.SparseRipsPersistence([metric, …]) Persistence diagrams resulting from Sparse Vietoris–Rips filtrations. Persistence diagrams resulting from Cech filtrations. Persistence diagrams resulting from filtered cubical complexes. Persistence diagrams resulting from filtrations of directed or undirected flag complexes.
