【导读】网上关于各种降维算法的资料参差不齐,但大部分不提供源代码。近日,有人在 GitHub 上整理了一些经典降维算法的 Demo(Python)集合,同时给出了参考资料的链接。

此外,作者还指出本次整理的降维算法实现环境为 Python3.6、ubuntu18.04(windows10) ,需要的库包括 numpy、sklearn、tensorflow 和 matplotlib,且具有以下特点:
-
每一个代码都可以单独运行,但是只是作为一个demo,仅供学习使用;
-
其中 AutoEncoder 只是使用 AutoEncoder 简单地实现了一个 PCA 降维算法,自编码器涉及到了深度学习领域,其本身就是一个非常大的领域;
-
LE 算法的鲁棒性极差,对近邻的选择和数据分布十分敏感;
-
2019.6.20 添加了 LPP 算法,但是效果没有论文上那么好,有点迷,后续需要修改。
