The key difference lies in their probability distributions: SNE uses Gaussian distributions for both high and low dimensions, resulting in crowded, poorly separated clusters. t-SNE replaces the low-dimensional Gaussian with a Student t-distribution, which has heavier tails that allow moderate-distance points to spread farther apart while keeping close neighbors together. This produces well-separated clusters and offers computational advantages by avoiding expensive exponential calculations. ## Full article daily.dev links to this article rather than hosting it.
