Webby Jake Hoare. t-SNE is a machine learning technique for dimensionality reduction that helps you to identify relevant patterns. The main advantage of t-SNE is the ability to preserve local structure. This means, roughly, that points which are close to one another in the high-dimensional data set will tend to be close to one another in the chart ... 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. WebApr 12, 2024 · tsne = TSNE (n_components=2).fit_transform (features) This is it — the result named tsne is the 2-dimensional projection of the 2048-dimensional features. n_components=2 means that we reduce the dimensions to two.
