This function performs dimensionality reduction using tSNE algorithm based on
the paper: Visualizing Data using t-SNE, Maaten et. al.
+ There exists a variant of t-SNE, implemented in sklearn, that first reduces the
+ dimenisonality of the data using PCA to reduce noise and then applies t-SNE for
+ further dimensionality reduction. A script of this can be found in the tutorials
+ folder: scripts/tutorials/tsne/pca-tsne.dml
+
+ For direct reference and tips on choosing the dimension for the PCA pre-processing,
+ you can visit:
