First, unlike PCE, t-SNE doesn't give an explicit transformation that you can reuse. So, if you have obtained some new data, the entire optimization has to start from the beginning. This is a problem because t-SNE can be really slowThe t-SNE algorithm was able to clearly represent all data points in a 2 dimensional space, and most of the data points of different features exhibited a short-line structure of one or several segments. The t-SNE algorithm clearly separated the different categories of data.Basic t-SNE projections¶. t-SNE is a popular dimensionality reduction algorithm that arises from probability theory.
