MIT Media Lab: Reality Mining
MIT Media Lab: Reality Mining The Reality Mining project at MIT uses the cell phones of students and Faculty to track their behavior and then predict their future behavior. They claim that it's accurate in predicting someone's next move 85% of the time. This is pretty poor performance. If I know the MIT student is in the lab, there's a 100% chance of correctly predicting their next activity will be to go to their dorm room. Similarly, if they are in the dorm, there's a 100% chance that they are going back to the lab. I'm guessing they had a bad sample set, and that 30% of the students were from Harvard and they had a 50/50 chance of predicting if they would show up at lab versus sleep in, or if they would go to a bar after lab or take the bus to Wellsley.
