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

Parameters:

handle Graph library L3 handle
sourceNUM Input, sourceIndices buffer length of source vertex
sourceIndices Input, source vertex’s out members
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 sparse graph
label Output, the predicted most similar label
