K-means 聚类算法 python 代码实现
你好,以下是基于能量距离的聚类算法的 Python 代码示例:
```python
import numpy as np
def energy_distance(x, y):
return np.sqrt(np.sum((x - y) ** 2))
def k_means_clustering(X, k):
n_samples, n_features = X.shape
centroids = X[np.random.choice(n_samples, k, replace=False)]
labels = np.zeros(n_samples)
while True:
for i in range(n_samples):
distances = [energy_distance(X[i], c) for c in centroids]
labels[i] = np.argmin(distances)
new_centroids = np.array([X[labels == j].mean(axis=0) for j in range(k)])
if np.allclose(new_centroids, centroids):
break
centroids = new_centroids
return labels
```
希望能对你有所帮助。
