Pete Warden explains a phenomenon:
One of the most frequent questions I get asked from people exploring machine learning beyond cloud and desktop machines is “What about training?”. If you look around at the popular frameworks and use cases of edge ML, most of them seem focused on inference. It isn’t obvious why this is the case though, so I decided to collect my notes in a post here, so I can have something to refer to when this comes up (and organize my own thoughts too!).
Pete’s reasons make sense. I think the last one is the most important.
