Visually exploring such high-dimensional data can then become challenging and even practically impossible to do manually. Hence it is essential to understand how to visualize high-dimensional datasets. t-Distributed stochastic neighbor embedding (t-SNE) is a technique for dimensionality reduction and ...
Amir et al. now report viSNE, a tool for the interpretation and visualization of high-dimensional data, in which single-cell resolution is maintained. The algorithm projects the data from h鈥doi:10.1038/nmeth.2540Amir, E.-a.DNature Methods...
步骤:首先构建KNN图,然后把图投影到低维空间。 创新点:提出了非常有效的算法对于KNN图的构建,提出了一个概率模型对于图的可视化。 实验证明:LargeVis在图构建和可视化上表现的都比T-SNE好。
VisuMap helps people to analyze high dimensional non-linear complex data with a collection of mapping, clustering algorithms and various data views.
类似t-SNE,本文以KNN图捕捉原始数据分布,但目标函数没有采用KL散度,但含义是类似地,只是更好地帮助训练,达成更快的速度和更稳定的参数。 对于相似度的度量主要是L2距离,无论在高维或者低维,不清楚在其他度量空间上是否有效。 相比于t-SNE,降维速度和参数稳定性有很大提升,但是仍然比较慢,测试1M,8线程要2-3个...

PHATE (Potential of Heat-diffusion for Affinity-based Trajectory Embedding) is a tool for visualizing high dimensional data. PHATE uses a novel conceptual framework for learning and visualizing the manifold to preserve both local and global distances. ...
The high-dimensional data created by high-throughput technologies require visualization tools that reveal data structure and patterns in an intuitive form. We present PHATE, a visualization method that captures both local and global nonlinear structure using an information-geometric distance between data ...
Visualizing Data using t-SNE 来自 arXiv.org 喜欢 1 阅读量: 16234 作者: van der Maaten, Laurens,Hinton, Geoffrey 摘要: We present a new technique called "t-SNE" that visualizes high-dimensional data by giving each datapoint a location in a two or three-dimensional map. The technique is...
