Webt-Distributed Stochastic Neighbor Embedding (t-SNE) in sklearn ¶. t-SNE is a tool for data visualization. It reduces the dimensionality of data to 2 or 3 dimensions so that it can be plotted easily. Local similarities are preserved by this embedding. t-SNE converts distances between data in the original space to probabilities.
