I have an array (X), contains scores values of 10 users with their score. I used Minimum Spanning Tree Clustering (MST) to cluster the users based on their values. MST did not cluster the data, return 0 clusters instead!!!!
The following code:
import warnings
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns
from sklearn_extra.cluster import KMedoids
from tabulate import tabulate
from termcolor import colored, cprint
from prettytable import PrettyTable
from mst_clustering import MSTClustering
%matplotlib inline
warnings.filterwarnings('ignore')
X = np.array([0.85142858,0.85566274,0.85364912,0.81536489,0.84929932,0.85042336,0.84899714,
0.82019115, 0.86112067,0.8312496 ])
X=X.reshape(-1, 1)
MST = MSTClustering(cutoff_scale=2, approximate=False)
labels = MST.fit_predict(X)
dfMST= pd.DataFrame(zip(labels,X))
dfMST = dfMST.rename({0: 'cluster', 1: 'values'}, axis=1)
dfMST['user'] = dfMST.index
dfMST = dfMST[['cluster', 'user', 'values']]
print ('clustering the data using MST')
print(tabulate(dfMST, headers='keys', tablefmt='psql'))
produced the output as follows:
clustering the data using MST
+----+-----------+--------+----------+
| | cluster | user | values |
|----+-----------+--------+----------|
| 0 | 0 | 0 | 0.851429 |
| 1 | 0 | 1 | 0.855663 |
| 2 | 0 | 2 | 0.853649 |
| 3 | 0 | 3 | 0.815365 |
| 4 | 0 | 4 | 0.849299 |
| 5 | 0 | 5 | 0.850423 |
| 6 | 0 | 6 | 0.848997 |
| 7 | 0 | 7 | 0.820191 |
| 8 | 0 | 8 | 0.861121 |
| 9 | 0 | 9 | 0.83125 |

How could I cluster users by MST in the correct way? should I suppose specify other cutoff scale parameters?
