What are the hot topics in Machine Learning Papers?

NIPS (which stands for "Neural Information Processing Systems") is an annual conference on machine learning and computational neuroscience, and papers presented there reveal what experts in the field are working on. Conveniently, you can find the data from the 2015 conference from Kaggle's NIPS 2015 Papers page. Let's load the data downloaded from Kaggle to the current folder. I also wrote a script nips2015_parse_html in order to parse the HTML file "accepted_papers.html" We can visualize which organization the authors of accepted papers belong to using graphs.
