Student t-distribution t-SNE在高维空间下使用高斯分布将距离转换为概率分布,在低维空间下使用偏重长尾分布的t分布将距离转换为概率分布。使用t分布的联合概率qij可以表示为: qij=(1+||yi−yj||2)−1∑k≠l(1+||yk−yl||2)−1 这样损失函数的梯度为: ∂C∂yi=4∑j(pij−qij)(yi−yj...

t-SNE has become a very popular technique for visualizing high dimensional data. It’s extremely common to take the features from an inner layer of a deep learning model and plot them in 2-dimensions using t-SNE to reduce the dimensionality. Unfortunately, most people just use scikit-learn’...
t-SNE has a hyper-parameter called perplexity. Perplexity balances the attention t-SNE gives to local and global aspects of the data and can have large effects on the resulting plot. A few notes on this parameter: It is roughly a guess of the number of close neighbors each point has. Th...
Here we describe how to circumvent such pitfalls, and develop a protocol for creating more faithful t-SNE visualisations. It includes PCA initialisation, a high learning rate, and multi-scale similarity kernels; for very large data sets, we additionally use exaggeration and downsampling-based ...
