Tech Talk: Googlers Are Becoming Machine Learning Ninja Androidheadlines.com

Code for machine learning is done in algorithms. Ideally, it should be elegant, beautifully efficient and, if it's doing its job well enough, you shouldn't even notice it's there while the machine is doing its thing. The only trace of the code that should be present is what the code is there for; to enable the machine to learn and think. A certain class of historical warriors were quite similar; they were brutally efficient, worked elegantly, and kept their presence hidden. One could only venture a guess that they had been there, if they did their job well, and a nebulous guess at that.
