"Rube Goldberg Machine Learning" comes to web performance analytics

Note: The title of this article is a play on the term "Rube Goldberg machine". Acccording to Wikipedia, a Rube Goldberg machine is a contraption, invention, device, or apparatus that is deliberately over-engineered to perform a simple task in a complicated fashion, generally including a chain reaction. Keep that in your mind. Everyone (that cares about ML) knows about supervised / unsupervised / semi-supervised learning pipelines. I have now come across an entirely new class of ML pipelines that I shall call "Rube Goldberg Machine Learning" pipelines.
