Hello @Blake Pollard, thanks a lot for sharing your experience. Is there a paper related to it? Concerning categories, my initial intuition is that it can help me to gain a more realistic and important insight on machine learning and it would be my pleasure if I could try to contribute with some workgroup (is it already running?) in both fronts that you did cite. I have been drafting ideas but it would require some exchange by email... could you please send yours for me? best
