我正在使用马尔科夫聚类来聚拢一个878个节点的图。其实现是基于这里提到的工作 https:/github.comguyallardmarkov_clustering
adj_matrix = nx.to_numpy_matrix(G)
res = mcl.run_mcl(adj_matrix)
clusters = mcl.get_clusters(res)
集群。
[(0,73, 88,173,223,235,390,405,409,435,442,456,481,501,573,615),
(5, 38, 193, 403, 657, 679, 760, 791, 835, 854),
...
...
(7, 201, 640)]
看起来程序给我的节点顺序不是我用来建立图的原始标签,它是这样的: 780873982
, 928735728
, 293482978
等,有没有办法将上述结果映射到原始节点标签上?
预计结果会是这样的
[(780873982, 928735728, 293482978), (293482932, 883482978), ...]
先谢谢你!
你可以使用一个字典。
# dummy nodes and graph
nodes = [np.random.randint(0,10031) for a in range(100)]
G = nx.Graph()
G.add_nodes_from(nodes)
# dummy clusters
clusters = [list(np.random.choice(range(len(G.nodes)), np.random.randint(1,5))) for a in range(8)]
# make mapping dictionary:
mapping = {a:b for a, b in zip(range(len(G.nodes)), G.nodes())}
# apply mapping_dictionary:
clusters_with_node_names = []
for c in clusters:
clusters_with_node_names.append([mapping[a] for a in c])
