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
