In closing, it's only fair to mention that MachineBox does have some limitations for its free tiers; but for personal projects, in my experience, you won't run into them. Despite my personal reservations on the various machine learning-as-a-service systems out there, I do think they provide value. I have used them from time to time, but I generally do not need them. Nevertheless, I highly recommend that the reader check them out.
This chapter, in combination with the previous chapter, has shown the breadth of machine learning in the industry. Not all machine learning algorithms have to be handwritten from scratch if your main problem does not call for it. I am lucky enough to have a career in doing what I love: building customized machine learning algorithms. This may have tainted my views on this issue. You may be an engineer on a deadline who has to solve some...
