I'm not sure this is correct. I come from the optimal control world. The problem is not unconstrained and definitely does not have infinite variables (if you think in state-space, consider the state-space equation x' = f(x, u, theta). The x-space (state) is large but finite, and the u-space is fairly small -- steering, gear, brake, etc.). The x-space is also stochastic, and there are many observability issues.
That said, we've been designing control systems against the real world for a number of years now, and the key is not to model all the unknowns (because there will always be something you can never anticipate), but to model the known and safe path that the system can fall back to.
The problem is a complicated one, and it will take more than several attacks to make it work, but it is not by any means an impossible one if you break it down into the fundamentals.
- seibelj 8y agoI could not disagree more. The input to an AV’s sensors, not just the data but what it represents and must be determined, is infinite. If your solution is to stop the car, you must also determine if that’s safe to do. It’s extraordinarily complex. This isn’t a factory.
- wenc 8y agoI strongly disagree. It is a large set but not infinite, otherwise humans would not be able to drive. It is constrained by physical laws. Also, control systems have been used to control much more complex entities than just factories. I agree it is an extraordinarily complex problem. But I also believe progress can be made to a point where it can be feasibly solved.
