可以的,hits算法的python实现如下:
```python
import numpy as np
def hits_algorithm(adjacency_matrix, max_iterations=100):
num_nodes = adjacency_matrix.shape[0]
authority_scores = np.ones(num_nodes)
hub_scores = np.ones(num_nodes)
for i in range(max_iterations):
# Authority Update Step
hub_scores = np.dot(adjacency_matrix, hub_scores)
norm = np.linalg.norm(hub_scores)
hub_scores = hub_scores / norm
# Hub Update Step
authority_scores = np.dot(adjacency_matrix.T, authority_scores)
norm = np.linalg.norm(authority_scores)
authority_scores = authority_scores / norm
return authority_scores, hub_scores
```
以上是一个简单的实现,其中 `adjacency_matrix` 是节点之间的关系矩阵。
