Tsne r wrapper

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. Webscanpy.external.pp.bbknn. Batch balanced kNN [Polanski19]. Batch balanced kNN alters the kNN procedure to identify each cell’s top neighbours in each batch separately instead of the entire cell pool with no accounting for batch. The nearest neighbours for each batch are then merged to create a final list of neighbours for the cell.
