James Padolsey that’s a bit worrying for me considering I intended this for software engineers, not academics. Would be great if you could tell me on what concepts I need to improve on. These days I care less about the maths and think of DL as lego blocks that I put together (don’t care what the individual block is made of). Also there is DataCamp where the first few lessons are free, and might make it easiser to do everything here.
