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.
WebNov 29, 2024 · What is t-SNE? t-SNE is an algorithm that takes a high-dimensional dataset (such as a single-cell RNA dataset) and reduces it to a low-dimensional plot that retains a lot of the original information. The many dimensions of the original dataset are the thousands of gene expression counts per cell from a single-cell RNA sequencing experiment. fnf fire fight part 3WebEach plot is showing the distribution of raw values only, for whichever set of data you use.
