t-SNE - Visualizing Data using t-SNE Flick CS Phd in Westlake University 4 人赞同了该文章 SNE (Stochastic Neighbor Embedding) SNE把数据点之间的高维Euclidean距离转化为表示相似度的条件概率。数据点xi和数据点xj之间的相似度可以用pj|i表示:对于相距较近
Visualizing data using t-SNE[J]. Journal of Machine Learning Research, 2008: 2579-2605. 概 t-sne是一个非常经典的可视化方法. 主要内容 我们希望, 将高维数据X={x1,x2,…,xn}X={x1,x2,…,xn}映射到一个低维空间Y={y1,y2,…,yn}Y={y1,y2,…,yn}, 同时保留相关性(这里的相关性就不局限...
最后迭代公式用了momentum [ ag{7} mathcal{Y}^{(t)}=mathcal{Y}^{(t)} + eta frac{delta C}{delta mathcal{y}} +alpha (t) (mathcal{Y}^{(t-1)} - mathcal{Y}^{(t-2)}). ] t-SNE 由于crowding problem (好像是指高维数据映射到低维数据发生重叠). 为了解决这种问题, 作者采用了俩...

VISUALIZING DATA USING T-SNE 2. Stochastic Neighbor Embedding Stochastic Neighbor Embedding (SNE) starts by converting the high-dimensional Euclidean dis- tances between datapoints into conditional probabilities that represent similarities. 1 The similarity of datapoint x j to datapoint x i is the co...
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 ...
different, but related, low-dimensional manifolds, such as images of objects from multiple classes seen from multiple viewpoints. For visualizing the structure of very large data sets, we show how t-SNE can use random walks on neighborhood graphs to allow the implicit structure of all of the ...
