示例1: dendrogram
# 需要导入模块: from sklearn.cluster import KMeans [as 别名]
# 或者: from sklearn.cluster.KMeans import plot_k_sse [as 别名]
dendrogram(links)

knn(meta[liwc], labels=meta['Name of Work'].values)
'''K-means'''
k = KMeans(n_clusters=5) # 5 is at an elbow for sse in 2-d
km = k.fit_transform(truncatedFeatures)
'''PCA'''
pca, X_pca, k, km = kcluster(justDFeatures, n_clusters=8)
print features.columns[np.argsort(pca.components_[0])[:100]]
# plt.savefig("scree.png", dpi= 100)
pca = decomposition.PCA(n_components=2)
X_pca = pca.fit_transform(X_centered)
plot_embedding(X_pca, y)
k.plot_k_sse(X_pca) # for 2 components 5 clusters
''' Supervised Learning'''
# Logistic Regression and Random Forest seem to perform the best
# Nonfiction seems unpredictable, while fiction, letters and poetry
# are somewhat predictabe
