event <int> cosineSimilarityAPSparse ( xf::graph::L3::Handle& handle, uint32_t topK, xf::graph::Graph <uint32_t, float> gr, uint32_t** resultID, float** similarity )
The all-pairs cosine similarity API for sparse graph.
Parameters:
| handle | Graph library L3 handle |
| topK | Input, the output similarity buffer length |
| gr | Input, CSR graph of IDs’ type of uint32_t and weights’ type of float |
| resultID | Output, the topK highest similarity IDs of all vertices in the sparse graph |
| similarity | Output, similarity values of all vertices in the sparse graph |
