Personally I am curious how this is done in the AI. Do they simply flip a switch that says “if you see stop sign make a full stop,” or do they now have to update and retrain the neural net to acquire this behavior. Does anyone know?

- czr 5y agothey flipped a switch (this one, under "clear to go" subheading https://youtu.be/ToDMceo0aDs?t=20 https://youtu.be/ToDMceo0aDs?t=20). tesla planning still mostly is done by C/C++ code.
- wcoenen 5y agoThere is a mix of a "neural net planner" and a "explicit planning and control" in traditional code[1]. The explicit planner has the last word, and uses input from both the "vector space" and the neural net planner. Karpathy has commented about the neural nets gradually replacing the traditional code. See his presentation[2] around 18:45.
