t-SNE evaluation about 2017-spatialmap-robin

[Kohze]

Did a first test run on 5 Datasets and will run over some night the next days the same procedure over all datasets (or directly on a server).

The TSNE: The perplexity fixed to 35 and the iterations indicated on top of each plot.

As comparrison the PCA of the same data.

It is important in such cases to be systematic. Best approach would be to do this analysis for each dataset separately, and for a range of perplexities and steps, as the number of step to converge will depend on the perplexity itself.
