WebLet's see how it works for our distance matrix, using the precomputed dissimilarity to specify that we are passing a distance matrix: In [8]: ... This is implemented in sklearn.manifold.TSNE. If you're interested in getting a feel for how these work, I'd suggest running each of the methods on the data in this section. WebPca，Kpca，TSNE降维非线性数据的效果展示与理论解释前言一：几类降维技术的介绍二：主要介绍Kpca的实现步骤三：实验结果四：总结前言本文主要介绍运用机器学习中常见的降维技术对数据提取主成分后并观察降维效果。我们将会利用随机数据集并结合不同降维技术来比较它们之间的效果。
