I see what you mean. I think it's because NN is driving much of the research in the ML field. I wanted Data Prism to be a newsletter about where the industry is headed. About startups, new projects receiving attention (and funding), things that are really working and topics that the (non-technical) media is talking about. That's the difference between Data Prism and other (excellent) newsletters I receive, which are a bit more technical/academic. But still, I agree we hear a lot about deep learning and DNN lately. Maybe because people are fascinated by this new, "mysterious" technology? Or because companies claim they use it even if they're using simpler ML models?
