22. python - How can i plot a Kmeans text clustering result with matplotlib? - Stack Overflow

    In your example if you use PCA to initialize your t-SNE you get widely spaced centroids; if you use random initialization you'll get tiny centroids and an uninteresting picture.

25. python - import matplotlib.pyplot hangs - Stack Overflow

    You can fix the problem on Mac OS X Mavericks and Yosemite by doing the following:
    
    cd ~/.matplotlib/
    fc-list # Should take a couple minutes.
    After fc-list finishes running you will be able to import the package using import matplotlib.pyplot as plt.

27. word2vec-pride-vis/tsne.py at master · arnicas/word2vec-pride-vis

    I used a Python t-SNE library to reduce the 200 feature dimensions for each word to 2 dimensions and plotted them in matplotlib. I saved out the x/y coordinates for each word in the book, so that I can show those words on the graph as you mouse over the replaced (blue) words.
