Vannevar Bush, Topic Transparency, Ancient Maps, and Concussion Sensors
- As We May Think (Vannevar Bush) — incredibly prescient piece he wrote for The Atlantic in 1945.
- Transparency and Topic Models (YouTube) — a talk from DataGotham 2012, by Hanna Wallach. She uses latent Dirichlet allocation topic models to mine text data in declassified documents where the metadata are useless. She’s working on predicting classification durations (AWESOME!). (via Matt Biddulph)
- Slippy Map of the Ancient World — this. is. so. cool!
- Technology in the NFL — X2IMPACT’s Concussion Management System (CMS) is a great example of this trend. CMS, when combined with a digital mouth guard, also made by X2, enables coaches to see head impact data in real-time and asses concussions through monitoring the accelerometers in a players mouth guard. That data helps teams to decide whether to keep a player on the field or take them off for their own safety. Insert referee joke here.
