This method assumes a global embedding function in low dimensional space, then incorporates the relative compactness information of the data distributions on the global geometry to reconstruct sample data. Finally, the global low dimensional submanifold is obtained by minimizing the cost function.

该方法首先假定目标空间的整体映射函数，然后结合数据的全局几何结构分布信息进行数据重构，最后通过最小化准则函数来得到嵌入高维空间的低维子流形。

Carl Ludwing explains how this technique differs from traditional texture mapping : when you want something to be in a certain area, like a grease spot, everyone else tends to do it with standard texture-mapping tools. But if I take a painted map and map it on, then I've wrapped a two-dimensional object around a three-dimensional object, and there are all sorts of positioning problems associated with that. Also, when you transition to another subpart of the character, you have to provide a whole new set of coordinates.

卡尔·路德温解释了这一技术与传统材质贴图技术的不同之处，比如说：如果想把油点一类的东西贴到某个地方，别人都会用标准的材质贴图工具来完成，但是如果我先拿来一张着色的地图，把这个油点标在上面，那就等于把一个三维物体安置在二维环境当中，随之会出现各种定位方面的问题，同样，如果你要观察目标的另一处次要部位，就必须给出新的坐标。
