我正在使用ELKI进行大约14,000个GPS点的DBSCAN聚类。它运行正常,但我希望看到有关群集的信息,例如群集中有多少点。?
答案 0 :(得分:1)
如果您使用-resulthandler ResultWriter
并输出到文本,则群集大小将位于每个群集文件的顶部。
可视化工具目前似乎无法显示群集大小。

如果使用-resulthandler ResultWriter并输出到文本,则群集大小将位于每个群集文件的顶部。
此外,如果您想将所有这些结果合并到一个文件中,这里有一个有效的python脚本:
clusterout_path = "path/to/where/files/all/go/"
finalout_path = "/path/for/single/merged/file/"
consol_filename= "single_merged_file.txt"
cll_file = open(finalout_path + consol_filename,"a")
cll_file.write("ClusterID"+ "\t" + "Lon" + "\t" + "Lat" + "\n")
def readFile(file):
f = open(clusterout_path + file)
counter = 0
cluster = ""
lon = ""
lat = ""
for line in f.readlines():
counter+=1
if counter == 1:
cluster = line.split(":")[1].strip().lower()
if counter > 4 and line.startswith("ID"):
arr = line.split(" ")
lon = arr[1]
lat = arr[2]
cll_file.write(cluster + "\t" + lon + "\t" + lat + "\n")
f.close()
listing = os.listdir(clusterout_path)
for infile in listing:
print "Processing file: " + infile
readFile(infile)
cll_file.close()
