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 |
