降维。例如很多问题在n维上解决很复杂，我们就使用某种方法将其降到n-1维或更小的维数上，可以降低问题的复杂度。
专辑名:Dimension Reduction 歌手:3He 发行时间:2018-12-31 简介:在2018年的最后一天,Ran Music 带来了电子新人 3He 的第二张 EP 《Dimension Reduction》(降维),这张 EP 延续了 3He 在夏日发布的处女作 《Mirror Image》的智能舞曲风格,收录了两首他利用最新的模块合成器、音序器制作的全新单曲。 不同于《...
这样,从一个(高维)图片到一个各个属性概率(低维)就是一个Dimension Reduction。 四Dimension Reduction 为什么说降维是很有用的呢? 有时候在3D很复杂的图像到2D就被简化了。 在MNIST训练集中,很多28*28维的向量转成一个image看起来根本不像数字,其中是digit的vector很少,所以或许我们可以用少于28*28维的向量来描...

For both dimension reduction methods, the methods include the Broken-Stick Method and Bartlett's Test of Sphericity. For PCA, a permutation test is also performed if the Number of Permutations parameter value is greater than zero. Information about the results of each test are displayed as ...
Through a series of posts, learn how to implement dimension reduction algorithms using IsoMap.
Advances in single-cell transcriptomics provide an unprecedented opportunity to explore complex biological processes. However, computational methods for analyzing single-cell transcriptomics still have room for improvement especially in dimension reduction, cell clustering, and cell–cell communication inference....
