So here I am in Sunnyvale, California. It is 2:42 p.m. local time. In the evening, I will be attending the Science Foo Camp sponsored by Google and Nature. After I am done with this blogging, I will most probably take a nap, as I could not get adequate sleep on the plane.
I originally thought of hiring a car, but then judged it was probably too much trouble. Therefore I took a cab instead. I always enjoy conversation with the driver.
We were discussing the high tech devises on the car. The driver pointed to a camera and said it captured 8 hours of video, looping. "Do you get any strange customers?" I asked. "Yes", the driver said. "Especially at night. You know when people are loaded, when they are drunk, they sometimes behave strangely. But you can tell pretty well whether a guy is going to behave strangely when he is standing on the road." "Really?" "Oh, yeah. When a guy is waving his hand like that, or is standing in the middle of road, you can pretty well tell that he is going to make trouble. I just pass by them."
So it appears that this taxi driver has developed a cognitive filtering machine, telling potentially troublesome customers beforehand. A good adaptation. I am curious about the specific details for classification, though.
