topobench.transforms.liftings.graph2hypergraph.knn_lifting module#
This module implements the HypergraphKNNLifting class.
- class Graph2HypergraphLifting(**kwargs)#
Bases:
GraphLiftingAbstract class for lifting graphs to hypergraphs.
- Parameters:
- **kwargsoptional
Additional arguments for the class.
- __init__(**kwargs)#
- class HypergraphKNNLifting(k_value=1, loop=True, **kwargs)#
Bases:
Graph2HypergraphLiftingLift graphs to hypergraph domain by considering k-nearest neighbors.
- Parameters:
- k_valueint, optional
The number of nearest neighbors to consider. Must be positive. Default is 1.
- loopbool, optional
If True the hyperedges will contain the node they were created from.
- **kwargsoptional
Additional arguments for the class.
- Raises:
- ValueError
If k_value is less than 1.
- TypeError
If k_value is not an integer or if loop is not a boolean.
- __init__(k_value=1, loop=True, **kwargs)#
- lift_topology(data)#
Lift a graph to hypergraph by considering k-nearest neighbors.
- Parameters:
- datatorch_geometric.data.Data
The input data to be lifted.
- Returns:
- dict
The lifted topology.
