This is a really cool project and a nice writeup. What were the biggest lessons learned from a machine learning and computer vision standpoint?

- jacquesm 9y agoThat feature engineering is mostly dead, that ML is now accessible even to noobs like me (thanks to http://course.fast.ai/ http://course.fast.ai/ and other), that you don't need to build stuff like this in C or C++ any more to get decent speed. The machine learning itself: models are hard to train, harder than you'd think at first glance, that you need a lot of data for training and if your particular application does not have any samples then you're going to have to come up with clever ways of making images because the quantities needed are not something you can just go and shoot by hand. Also, that bootstrapping is a viable method, that way the machine does the hard part and you only have to correct, this takes the sting out of 90% or so of the work of labeling a dataset.
