StatQuest: t-SNE, clearly explained!

Here’s how to create a t-SNE graph in R (this is copied from the help file for Rtsne)…

library("Rtsne")
iris_unique <- unique(iris) # Remove duplicates
iris_matrix <- as.matrix(iris_unique[,1:4])
set.seed(42) # Set a seed if you want reproducible results
tsne_out <- Rtsne(iris_matrix) # Run TSNE
 
# Show the objects in the 2D tsne representation
plot(tsne_out$Y,col=iris_unique$Species)
