我们可以使用监督学习方法来预测用户的关注行为。例如,我们可以使用逻辑回归模型来预测用户是否会关注某个帖子。以下是一个简单的代码实例:
```python from sklearn.linearmodel import LogisticRegression from sklearn.modelselection import traintestsplit from sklearn.metrics import accuracy_score
data = load_data()
Xtrain, Xtest, ytrain, ytest = traintestsplit(data.features, data.labels, testsize=0.2, randomstate=42)
model = LogisticRegression() model.fit(Xtrain, ytrain)
ypred = model.predict(Xtest)
accuracy = accuracyscore(ytest, y_pred) print("Accuracy:", accuracy) ```
我们可以使用无监督学习方法来发现社交网络中的社群结构和特征。例如,我们可以使用聚类算法来发现社群。以下是一个简单的代码实例:
```python from sklearn.cluster import KMeans from sklearn.preprocessing import StandardScaler
data = load_data()
scaler = StandardScaler() datascaled = scaler.fittransform(data.features)
model = KMeans(nclusters=3) model.fit(datascaled)
labels = model.predict(data_scaled)
inertia = model.inertia_ print("Inertia:", inertia) ```
我们可以使用无监督学习方法来推荐内容相似性高的内容。例如,我们可以使用欧氏距离来计算内容之间的相似度。以下是一个简单的代码实例:
```python from sklearn.metrics.pairwise import euclidean_distances
data = load_data()
distances = euclidean_distances(data.features)
neighbors = np.argsort(distances, axis=1)[:, :5]
recommended_contents = data.contents[neighbors.flatten()] ```
