Volinsky: AT&T always processes mobile network data anonymously

Volinsky: AT&T plans to sell mobility analytics services to municipalities
“Now there's another part, you know, for the services that we might provide to a town or a municipality, that we would sell as a service.”
Volinsky: Cell tower location data pegs users roughly within a square kilometer
“And so that might peg you down to roughly within a square kilometer less if you're in New York, more if you're in a suburban or rural area.”
Volinsky: Earth Mover's Distance Is a Brilliant Metric for Data Science
“If you've, if you're working in a, if you're doing data science and you need a good distance metric, this, look at the earth mover distance. I had never heard of it before, and it's a brilliant, brilliant piece of science that's, of course, decades old.”
Volinsky: AT&T is developing synthetic datasets to share mobility data safely
“So a project we're working on this year is to create what we call synthetic data, it's just a fancy word for simulated data. What we want to do is create a simulated data set That looks very much like the data that we have, but isn't.”
Volinsky: AT&T Labs recently moved into a 30-story windowless building in Tribeca

“Chicago is one of the first players. They have online a whole bunch of crime statistics. You can go and download the data. They have APIs to it.”
Volinsky: Boston uses Street Bump to improve pothole repair efficiency
“Boston has this thing called Street Bump where you can report potholes so that when they send out pothole crews, they can be more efficient in, in filling those potholes.”
Volinsky: AT&T cell data shows Morristown High School activity spikes
“This was pointed at Morristown High School. So the three spikes on the bottom are texting spikes at the beginning of the day, before school started, during the lunch hour, and when they get out of school. And then you see when they get out of school at two 30,…”
AT&T Labs Drove 12 Morristown Routes 10 Times for Cell Training Data
“We went out and we drove each of these 12 routes 10 times each with two phones in the car, making calls, and GPS running on each one, and to get our training set to understand if you're on this route, what does the cell tower handoff sequence look like?”
