event <int> knnSimilarityAPSparse (
    xf::graph::L3::Handle& handle,
    uint32_t topK,
    xf::graph::Graph <uint32_t, float> gr,
    std::string* knownLabels,
    std::string* label
    )

The all-pairs k-nearest neighbors API for sparse graph. knnSimilarity API is based on the cosine similarity algorithm.

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
knownLabels	Input, labels of each vertex in the dense graph
label	Output, the predicted most similar labels of all vertices in the dense graph
