Jupyter notebook with the project work carried out during the first SUNDIAL training school in Groningen 22-26 January 2018. We used PCA and t-SNE to visualize tabular data of the Spitzer Survey of Stellar Structure in Galaxies (S4G). Data are taken from here.

To install the python dependencies you can use conda:
conda create -n tsne python=3 jupyter sklearn astropy matplotlib numpy pandas seaborn
conda activate tsne # or source activate if conda<4.4
