`fuzzy-c-means` is a Python module implementing the [Fuzzy C-means][1] clustering algorithm.

## instalation
the `fuzzy-c-means` package is available in [PyPI](https://pypi.org/project/fuzzy-c-means/). 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:
```Python
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()
```
