StatQuest: t-SNE, clearly explained!

By request, here are the powerpoint slides! If you download them, please encourage anyone you share them with to watch the video and subscribe to my YouTube channel. These metrics are important to justify the time I spend on StatQuest.

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)
