Pythonを使用して、単一の属性に基づいてJSONデータを3つのクラスタにクラスタリングする

データは次のようになります。

次のスクリプトを使用して JSON として処理されます。

import json
import pprint
import collections
import itertools

with open('toy.json', 'rb') as inpt:

    dict_hash_gas = list()
    for line in inpt:
        resource = json.loads(line)
        dict_hash_gas.append({resource['hash']:resource['gas']})

# Count up the values
counts = collections.Counter(v for d in dict_hash_gas for v in d.values())

counts = counts.most_common()

# Apply a threshold
threshold = 1000
counts = [list(group) for val, group in itertools.groupby(counts, lambda x: x[1] > threshold) if val]

# print(counts)

# resort the list by the magnitude of the manifest values
# as opposed to the frequency 
counts[0].sort(key=lambda x:int(x[0]))

# print(counts)

gas 変数に基づいて、データを3つの別個のクラスタに分割することはどのように可能ですか?

1 答え

  1. データを並べ替える
  2. カーネル密度推定を実行する
  3. 密度最小値を求めます。これらは最適な分割点です。
  4. データを分割する
