Towards Cost-Optimized Artificial Intelligence

If accuracy improves with more computation, why not throw in more time, people, hardware, and the concomitant energy costs? Seems reasonable but this approach misses the fundamental point of doing machine learning (and more broadly, AI): as a means to an end.  And so we need to have a little talk about cost-optimization, encompassing a much wider set of cost-assignable components than usually discussed in academia, industry, and the press. Viewing AI as a global optimization over cost (ie., dollars) puts the work throughout all parts of the value chain in perspective (including the driving origins of new specialized chips—like IBM TrueNorth Google’s Tensor Processing Unit). Done right it will lead to, by definition, better outcomes. The broad artificial intelligence landscape, to zeroth order, is focused around optimization of some…
