Isomap流形降维算法，包括了一个瑞士卷生成数据，dijk距离算法。-Dimensionality reduction algorithm Isomap manifold, including the formation of a Swiss roll data, dijk distance algorithm.

此文件包含生成swissroll数据集,并用LLE算法进行降维处理,很实用,应该对现在学习流形学习的同学有帮助。-This file contains data sets generated swissroll and dimensionality reduction algorithm with the LLE process, it is useful, it should now learning manifold learning for students help.

流形学习，非线性降维方法ISOMAP，应用在经典的swiss roll data上，可观察到很好的映射效果-Manifold learning, ISOMAP nonlinear dimension reduction method, the application in the classic Swiss roll data, can be very good mapping effect was observed

这是瑞士卷数据集，isomap的原始数据集，mat格式，好用(Swiss roll data set in mat , originally used in ISOMAP)
