t-SNE is a popular data visualization/dimension reduction methods used in high dimensional data. In this tutorial I explain the way SNE, a method that is the foundation of t-SNE is constructed and then I explain how t-SNE is different and how it improves upon t-SNE. In addition to that I also provide some points on how t-SNE results should be interpreted carefully.
