### Persistence Landscapes¶

The persistence landscape has been introduced Bubenik etal. JMLR 2015 as an alternative to persistence diagrams. This approach aims at representing topological features in an Hilbert space, for which statistical learning methods can be directly applied.

Note that many other alternatives have been proposed: silhouettes, persistence images, cumulative peristence intensity function etc. Coming soon in Gudhi...
