SNE仍然存在难以优化和Crowding problem的问题。为了解决这些问题,t-SNE提出了:(1) 用对称的SNE损失函数;(2) 在计算两点在低维空间的相似度时,用Student-t分布替代高斯分布。 Symmetric SNE 在SNE中,损失函数的目标是最小化pj|i和qj|i的Kullback-Leibler距离之和;Symmetric SNE的替代做法是最小化高维空间的联合...

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...

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 ...
