topobench.transforms.liftings.hypergraph2combinatorial package#

Hypergraph2Combinatorial liftings with automated exports.

class Hypergraph2CombinatorialLifting(**kwargs)#

Bases: HypergraphLifting

Abstract class for lifting hypergraphs to combinatorial complexes.

Parameters:
**kwargsoptional

Additional arguments for the class.

__init__(**kwargs)#
class UniversalStrictLifting(**kwargs)#

Bases: Hypergraph2CombinatorialLifting

Lift hypergraphs to combinatorial complexes.

It works by assinging the smallest rank values such that subcells of any cell have strictly smaller rank.

Parameters:
**kwargsoptional

Additional arguments for the class.

__init__(**kwargs)#
lift_topology(data)#

Lift the topology of a hypergraph to a combinatorial complex.

It works by setting the rank of a hyperedge equal to the maximum of the ranks of its sub-hyperedges plus 1.

Parameters:
datatorch_geometric.data.Data

The input data to be lifted.

Returns:
dict

The lifted topology.
