jaccard_coefficients (ResourceHandle resource_handle, _GPUGraph graph, first, second, bool_t use_weight, bool_t do_expensive_check)
Compute the Jaccard coefficients for the specified vertex_pairs.
Note
Jaccard similarity must run on a symmetric graph.
Parameters#
- resource_handleResourceHandle
Handle to the underlying device resources needed for referencing data and running algorithms.
- graphSGGraph or MGGraph
The input graph, for either Single or Multi-GPU operations.
- first :
Source of the vertex pair.
- second :
Destination of the vertex pair.
- use_weightbool, optional
If set to True, compute the weighted jaccard_coefficients (the input graph must be weighted in that case). Otherwise, compute the un-weighted jaccard_coefficients.
- do_expensive_checkbool
If True, performs more extensive tests on the inputs to ensure validity, at the expense of increased run time.
Returns#
A tuple of device arrays containing the vertex pairs with their corresponding Jaccard coefficient scores.
