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)…

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

  1. I don’t suppose you could do another video on Locally Linear Embeddings, could you? I realize it’s similar to t-SNE, but it would be nice to have an intuitive yet substantive explanation of the similarities and differences.

    Great videos, btw!

    Thanks, John Strong


    • That’s a great idea. Someone else has already asked for me to do “isomap” dimension reduction, and Locally-linear embedding is related, so I’ll add it to the to-do list.
