Anomaly detection is a fancy phrase for noticing when something is different than usual. We use it mostly for technology, like a tablet or computer. We rely on this stuff because it’s important to know why things are odd.


If you think about it, parents are anomaly detectors. Like when my sons come home from school, it’s IMPERATIVE they eat a mountain of snacks IMMEDIATELY or they might PERISH. But sometimes one will skip the feast. This is off. Maybe something is wrong (he’s sick) or maybe it’s no big deal (he ate some snacks on the bus home).


As in life, just because something is different than “normal” doesn’t mean it’s bad. But if your job is to keep things running at their best, it’s good to know what’s happening and to take a quick look to make sure everything’s OK.
