One of those algorithms is called t-SNE (t-distributed Stochastic Neighbor Embedding). It was developed by Laurens van der Maaten and Geoffrey Hinton in 2008. You might ask “Why I should even care? I know PCA already!”, and that would … See more If you remember examples from the top of the article, not it’s time to show you how t-SNE solves them. All runs performed 5000 iterations. See more To optimize this distribution t-SNE is using Kullback-Leibler divergencebetween the conditional probabilities p_{j i} and q_{j i} I’m not going through the math here because it’s not important.
