Adding Machine Learning to a Web App by Richard Dallaway.
As Richard points out, the example is contrived and I don’t think you will be rushing off to add machine learning to a web app based on these slides.
That said, I think his point that you should pilot the data first is a good one.
If you mis-understand the data, then your results are not going to be very useful. Hmmm, maybe there is an AI/ML axiom in there somewhere. Probably already discovered, let me know if you run across it.
