奇怪的事,这两个集群在t-SNE图中看起来大小相同。t-SNE算法适应“距离”的概念适应数据集中的区域密度变化。结果它自然地扩大了密集的集群,收缩了系数的集群,平衡了集群的大小。需要明确的是,这与任何降维技术都会扭曲距离的一般事实不同,密度均衡通是通过设计发生的,并且是t-SNE的可预测特征。然而,底线是无法再t...
How to Use t-SNE Effectively Although extremely useful for visualizing high-dimensional data, t-SNE plots can sometimes be mysterious or misleading. By exploring how it behaves in simple cases, we can learn to use it more effectively. A popular method for exploring high-dimensional data is some...
This post is about how to use t-SNE so I'll be brief with the details here. You can easily skip this section and still produce beautiful visualizations. The t-SNE algorithm models the probability distribution ofneighborsaround each point. Here, the term neighbors refers to the set of points...

I used TSNE method to cluster my DataSet. X_embedded = TSNE(n_components=2, verbose=1, perplexity=10, n_iter=600).fit_transform(binary) kmeans = KMeans(init="k-means++", n_clusters=6, n_init=4) kmeans.fit(X_embedded) Why it just clusters my DataSet into 2...
