John Schrom is a data scientist, graduate student, and avid self-tracker. After taking a look at his historical weight data he decided to dig a bit deeper into the story. Luckily, in addition to collecting his weight (via a Withings scale), he’s also been using Foursquare to collect his geolocation history. With these two data sources in hand he asked himself, “What kind of places do I visit when I’m gaining or losing weight?” Watch this great talk talk recored at the Bay Area QS Meetup to learn how he used association rule mining to explore his data, and what he found. When you’re done with the video make sure to go and read his excellent write-up here.
