fuzzy-c-means 0.0.4

A simple implementation of Fuzzy C-means algorithm.

scikit-mlm

fuzzy-c-means is a Python module implementing the Fuzzy C-means clustering algorithm.

instalation

the fuzzy-c-means package is available in PyPI. to install, simply type the following command:

pip install fuzzy-c-means

basic usage

simple example of use the fuzzy-c-means to cluster a dataset in tree groups:

from fcmeans import FCM
from sklearn.datasets import make_blobs
from matplotlib import pyplot as plt
from seaborn import scatterplot as scatter


# create artifitial dataset
n_samples = 50000
n_bins = 3  # use 3 bins for calibration_curve as we have 3 clusters here
centers = [(-5, -5), (0, 0), (5, 5)]

X,_ = make_blobs(n_samples=n_samples, n_features=2, cluster_std=1.0,
                  centers=centers, shuffle=False, random_state=42)

# fit the fuzzy-c-means
fcm = FCM(n_clusters=3)
fcm.fit(X)

# outputs
fcm_centers = fcm.centers
fcm_labels  = fcm.u.argmax(axis=1)


# plot result
%matplotlib inline
f, axes = plt.subplots(1, 2, figsize=(11,5))
scatter(X[:,0], X[:,1], ax=axes[0])
scatter(X[:,0], X[:,1], ax=axes[1], hue=fcm_labels)
scatter(fcm_centers[:,0], fcm_centers[:,1], ax=axes[1],marker="s",s=200)
plt.show()
