=========================================================================
t-distributed stochastic neighborhood embedding (tSNE) (`scanpy.tl.tsne`)
=========================================================================

For making TSNE plots, please use `Scanpy PlotEmbed` with the output of this tool and enter "tsne" as the
name of the embedding to plot.

t-distributed stochastic neighborhood embedding (tSNE) (Maaten et al, 2008) has been
proposed for visualizating single-cell data by (Amir et al, 2013). Here, by default,
we use the implementation of *scikit-learn* (Pedregosa et al, 2011).

It yields `X_tsne`, tSNE coordinates of data.
