WebBasic t-SNE projections¶. t-SNE is a popular dimensionality reduction algorithm that arises from probability theory. Simply put, it projects the high-dimensional data points (sometimes with hundreds of features) into 2D/3D by inducing the projected data to have a similar distribution as the original data points by minimizing something called the KL divergence. WebSep 22, 2024 · Let’s start with a brief description. t-SNE stands for t-Distributed Stochastic Neighbor Embedding and its main aim is that of dimensionality reduction, i.e., given some complex dataset with many many dimensions, t-SNE projects this data into a 2D (or 3D) representation while preserving the ‘structure’ (patterns) in the original dataset.
