It converts affinities of data points to probabilities. The affinities in the original space are represented by Gaussian joint probabilities and the affinities in the embedded space are represented by Student's t-distributions.This paper examines two commonly used data dimensionality reduction techniques, namely, PCA and T-SNE. PCA was founded in 1933 and T-SNE in 2008, both are fundamentally different techniques. PCA focuses heavily on linear algebra while T-SNE is a probabilistic technique. The goal is to apply these algorithms on MNIST dataset and …The exact t-SNE method is useful for checking the theoretically properties of the embedding possibly in higher dimensional space but limit to small datasets due to computational constraints.

t-SNE is a popular dimensionality reduction method for, among many other things, identifying transcriptional subpopulations from single-cell RNA-seq data. However, the sensitivities of results to and the appropriateness of different parameters used have not been thoroughly investigated.For example, the t-SNE papers show visualizations of the MNIST dataset (images of handwritten digits). Images are clustered according to the digit they represent--which we already knew, of course. But, looking within a cluster, similar images tend to be grouped together (for example, images of the digit '1' that are slanted to the left vs. right).
