Via NYC Taxi Cab Analysis
Via is considering expanding its service to include rides to and from NYC airports (JFK, LaGuardia). We are trying to decide between these options and how to launch the option we choose, i.e. as part of our core service or as a separate service.

Predicting Geolocation of Next Attack
In 1981 Peter Sutcliffe was convicted of thirteen murders and subjecting a number of other people to vicious attacks. One of the methods used to narrow the search for Mr. Sutcliffe was to find a “center of mass” of the locations of the attacks. In the end, the suspect happened to live in the same town predicted by this technique. Since that time, a number of more sophisticated techniques have been developed to determine the “geographical profile” of a suspected serial criminal based on the locations of the crimes.
