Web30 de jan. de 2024 · The very first step of the algorithm is to take every data point as a separate cluster. If there are N data points, the number of clusters will be N. The next step of this algorithm is to take the two closest data points or clusters and merge them to form a bigger cluster. The total number of clusters becomes N-1. Webwhere. c i is the cluster of node i, w i is the weight of node i, w i +, w i − are the out-weight, in-weight of node i (for directed graphs), w = 1 T A 1 is the total weight, δ is the Kronecker symbol, γ ≥ 0 is the resolution parameter. Parameters. input_matrix – Adjacency matrix or biadjacency matrix of the graph.
