流形学习Manifold Learning

Rosy is going to describe what Manifold Learing is in the simplest terms.

Rosy 将用最简单的语言描述 Manifold Learing 。

什么是流形学习？ML？

        Firstly，there are two words Manifold and Learning.

        Needless to say, there are two steps of ML:

step 1: Manifold

        Imagination of the basketball Standing in three-dimensional space, stripes on the surface of the ball could be described by (x,y,z). However, the basketball made from a planar materials. 

        Thus, "the stripes of the basketball -> the stripes of the planar materials ", this process we name it "Manifold".

step 2: Learning:"the stripes of the basketball -> the stripes of the planar materials ".

Focus on " -> ", and "the stripes of the planar materials ", this process we name it "Learning".

首先，有两个词：流形和学习。

毋庸置疑，ML有两个步骤：

第 1 步：流形

       想象篮球站在三维空间中，球表面的条纹可以用（x，y，z）来描述。然而，篮球是由平面材料制成的。

        因此，“篮球的条纹->平面材料的条纹”，这个过程我们称之为“流形”。

第 2 步：学习：“篮球的条纹——>平面材料的条纹”。

        专注于“->”和“平面材料的条纹”，这个过程我们称之为“学习”。

核心？How？

        Follow some rules to calculate the distance of the stripes composed of spots,  for each spot, selecting the first few spots of the nearest distance to plan a local neighborhood As. The As is two-dimensional space, it is a mapping of three-dimensional space. 

        The Mapping is what we want.

        按照一些规则来计算由点组成的条纹的距离，对于每个点，选择最近距离的前几个点来规划局部邻域 As。As是二维空间，它是三维空间的映射。这个映射就是我们想要的。
