Webbt-distributed stochastic neighborhood embedding (tSNE) [Maaten08] has been proposed for visualizating single-cell data by [Amir13]. Here, by default, we use the implementation … Webbt-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.
