Webt-SNE uses a heavy-tailed Student-t distribution with one degree of freedom to compute the similarity between two points in the low-dimensional space rather than a Gaussian distribution. T- distribution creates the probability distribution of points in lower dimensions space, and this helps reduce the crowding issue. WebI have plotted a tSNE plot of my 1643 cells from 9 time points by seurat like below as 9 clusters. But, you know I should not expected each cluster of cells contains only cells from one distinct time point. For instance, cluster 2 includes cells from time point 16, 14 and even few cells from time point 12.
