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. WebEach plot is showing the distribution of raw values only, for whichever set of data you use. You used mtdataset and mytestset as input, so in each case you are only seeing the distribution for those images of course.
