Tsne feature
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 … Web5.

In this tutorial, we will learn how to perform tSNE in R without going into theoretical underpinnings of tSNE.
WebAfter checking the correctness of the input, the Rtsne function (optionally) does an initial reduction of the feature space using prcomp, before calling the C++ TSNE implementation. Since R's random number generator is used, use set.seed before the function call to get reproducible results.
