I would advise you read this short article How to Use t-SNE Effectively before you invest too much time trying to interpret the plots. In case you don't read it, you'll find that your t-SNE plot will change considerably based on your iterations, and perplexity. Webt-SNE uses the t-distribution in the projected space. In contrast to the Gaussian distribution used by regular SNE, this means most points will repel each other, because they have 0 affinity in the input domain (Gaussian gets zero quickly), but >0 affinity in the output domain. Sometimes (as in MNIST) this makes nicer visualization. sigma cars repairsWebMay 30, 2024 · t-SNE is a useful dimensionality reduction method that allows you to visualise data embedded in a lower number of dimensions, e.g. 2, in order to see patterns … sigma carpet manufacturing thailand co. ltd
