Why your machine learning model may be melting icebergs.

Like many of you in Towards Data Science, I am self-taught in machine learning and can remember the day I first left my laptop in model training, fan whirring away, to return hours later and find it still buzzing along. "Hmm", I thought, "maybe I need a GPU". Fellow DIY thinkers: it is not a good idea to try and rip apart an old Xbox, but you could build your own. On days even further in the past, energy usage for my family sometimes created a choice between playing video games and air conditioning: rainy summer afternoons with the Xbox fan and the additional external Xbox fan both battling for sound preeminence with video games and other electronic weapons. Those were the days before discussions about energy efficiency triggered a climate change debates.
