python降维——局部线性嵌入算法（LLE）

sklearn官网地址：https://scikit-/stable/modules/generated/sklearn.manifold.LocallyLinearEmbedding.html

使用案例：

import numpy as npfrom sklearn.manifold import LocallyLinearEmbeddingx = np.array([[-3, -1,1,3], [-2, -14,5,6], [-3, -2,1,3]])lle = LocallyLinearEmbedding(n_components=2, n_neighbors=2)x_reduce = lle.fit_transform(x)print(x_reduce)
