About the "FAKE" demo video being discussed here...
A redditor called PM_YOUR_NIPS_PAPER (clever nick btw) - who claims he is / was training Tesla's computer vision network - posted this controversial tidbit yesterday:
Ok I can accept the hard-coded GPS stuff.
But if this guy is for real... Man, a lot of time was wasted by a lot of people last fall "analyzing" the bounding boxes, the way the (demo) car seemingly detected the "motion flow" of surroundings, "lane lines", "road flow" etc. Was it actually just post production stuff? Some guy in a back room painting the video stream on his computer?
Seriously?
You think that the car draw square etc during your travel?
Not at all. Of course is post-production.
Ok, i understand that you see in all the sci-fi films that the computer draw lines around people etc, but it's done to show to HUMANS that it recognized it, but the car doesn't do it, it just 'detect' something and send some message like "human at coordinateX,X2,Y,Y2" and maybe it send the 'message' only if it's relevant like if it's in the path.
Now, it means that the car can't detect it? no.
Do you think that the square were painted by human following every single car in every frame? No, it's done by a software, probably the same software that's used on the car, just edited so it can output some more info so another software can draw the lines.
For the stop, yes i think they are hard-coded, in the way that you say "the stop is at coordinate X,Y", and at that coordinate it check the light ( or do you think that you can hard-code the state of the lamp? ), or do you think you can hard-code someone with the bike at coordinate X,Y? of course it's done by the car.
It's done everytime perfectly? probably not, that's why it's not in production.
And again, yes, of course the path is hard-coded, you have something like "turn here, and here, go straight here and here", but again, it's a problem?
Not at all.
Whene there is autonomous car, this "series of step" are simply what the navigator would pop-out, so no problem here, that's really the only part that's not a problem here.
To end this i just say that i'm with you, it's a video of "what could be when we solve some problem", not "what it's actually working", and it's ok.. it's implicit
