The twenty ninth Conference on Neural Information Processing Systems (NIPS), a single track machine learning and computational neuroscience conference, was held in Montreal, during a relatively balmy winter week, spanning December 7th to 12th. The conference saw a record number of attendees. As illustrated in the graph, during the last 14 years, there has been a steady increase in the number of attendees in all three categories -- tutorials, conference, and workshops; and biggest growth this year was in tutorials where the attendance doubled compared to the previous year!
