- That's right, 55 MPH for about 22 miles. The machine stayed in one
- lane, and a person had to take over when the style of the road
- changed. It was the left lane, because there were exits from the
- right lane and the system gets confused when presented with a fork in
- the road. It was a van steered by a neural network; the network was
- trained by watching a recording of the scenery and the steering wheel
- motions when a person drove on a road similar to the one that the
- network eventually drove. Check out Dean Pomerleau's thesis at CMU,
- if you want more details.

- This is at best marginally relevant to sci.nanotech. Followups to
- comp.ai.neural-nets, which Pomerleau reads (but I don't). Pomerleau
- looked at this post before I made it and agreed with my summary of his
- work.

- When they took the fourth amendment, I was silent because I don't deal drugs.
- When they took the sixth amendment, I kept quiet because I know I'm innocent.
- When they took the second amendment, I said nothing because I don't own a gun.
- Now they've come for the first amendment, and I can't say anything at all.
