WebJul 7, 2016 · Each color, in the picture below, represents one of the numbers, between 0 to 9. With PCA and ISOMAP you can see some groups like orange (number 1) or the red (number 0), are clearer than others, but with T-SNE the differentiation is amazing. Is important to realise that the algorithm only sees images of numbers.
