    )

The single source k-nearest neighbors API for dense graph. knnSimilarity API is based on the cosine similarity algorithm.

Parameters:

handle	Graph library L3 handle
sourceNUM	Input, sourceIndices buffer length of source vertex
sourceWeights	Input, weights of the source vertex’s out members
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 label
