WebBasic t-SNE projections¶. t-SNE is a popular dimensionality reduction algorithm that arises from probability theory. Simply put, it projects the high-dimensional data points (sometimes with hundreds of features) into 2D/3D by inducing the projected data to have a similar distribution as the original data points by minimizing something called the KL divergence. WebFeature extraction: mapping the original data to a new feature set. Feature selection : selecting a subset of attributes. In the machine learning literature the term dimensionality reduction is commonly associated with (typically) unsupervised methods that transform high-dimensional data to a lower dimensional feature set, whilst feature selection is …
