It's hard to disagree with your disagreements...Just for that I'm disagreeing with all your posts!
Speaking of the Gospel, has anyone ever told you how great your contributions are here on TMC??ok, I'm disagreeing with all your posts but I simply can't disagree with the Gospel!
Whether that actually existed online for more than a few minutes is the real question. My experience with making innocuous changes in OSM to things like speed limits is that the moderators take days and sometimes weeks to accept a change. And even valid changes are often rejected. I assume your post was designed to provide comic relief, as it does nothing to undercut the credibility of OSM. People are constantly messing with specific entries on Wikipedia, but every AI chatbot has vacuumed Wikipedia clean. And probably OSM also. Is that why chatbots hallucinate? I doubt it.

My guess is he means they are downsampling the camera video to the same resolution as HW3 before feeding it to the NNs. This allows them to train/test the NNs ONCE for both H3 and HW4, reducing training time and cost (which is very high).Right, that's great theoretically, but if you recall, I kinda brought this all up because Elon chose to use the term emulation. It could be absolutely nothing, just a simple term he figured everyone could understand and HW4 may have been designed from the ground up to be in "HW3 emulation mode" efficiently. I agree that this would make the most sense.
I'm curious how they're stitching the HW4 feeds to the NN in an emulated fashion. My understanding is that HW4 has 1 less front camera - HW3 had 3 forward cameras, 1 wide angle, 1 standard, and 1 narrow focus camera. HW4 has two front facing cameras (not sure if they are both standard, or is one wide angle).
If we assume that HW4 employs two cameras of different focal lengths (i.e. not the unlikely scenario of a left/right merged pair), then it's clear that one of these must be wide angle with essentially the same FOV as the HW3 wide camera. That camera can easily be binned or down-sampled to emulate the HW3 wide camera.My guess is he means they are downsampling the camera video to the same resolution as HW3 before feeding it to the NNs.

Nothing for me today.
As noted, one of the advantages of having higher-resolution cameras is that they can serve redundantly for the narrower-FOV cameras, and that's probably how Tesla was able to reduce from three to two physical front cameras from HW3 to HW4. What's more, it could allow the simulated narrow-FOV cameras to be "steered" within the wider-angle window. I've occasionally wondered whether a literally steerable telephoto camera might be a good idea, e.g. for reading street signs at a greater distance, though it's far from obvious how to train a network to effectively use such a thing? (But it is exactly how our eyes work; our brains control in real-time where to direct our "telephoto" foveas, which are a lot higher resolution than any FSD cameras.)If we assume that HW4 employs two cameras of different focal lengths (i.e. not the unlikely scenario of a left/right merged pair), then it's clear that one of these must be wide angle with essentially the same FOV as the HW3 wide camera. That camera can easily be binned or down-sampled to emulate the HW3 wide camera.
The remaining question is whether the second front HW4 camera has a medium or a narrow (tele) FOV (or perhaps some compromise intermediate FOV). Any of these possibilities can achieve HW3 emulation/compatibility, with the simplest solution being
Again it may not be quite this simple based on the actual HW4 setup - but something tells me that this simplification opportunity would have been carefully considered by the team during the HW4 planning, so I don't think it's an unreasonable speculation.
- 2x2 -> 1x1 binning to emulate whichever HW3 camera whose FOV closely matches one of the HW4 cameras.
- A simple 2X crop (possibly shifted up or down for aim-point matching) to emulate either
- the medium HW3 cam using the wide HW4 cam, or
- the narrow HW3 cam using the medium HW4 cam.
The dummy third camera location may be evidence that the final design came late in the HW4 development. Or, it may be evidence that something else is yet to come, like a super night-vision camera, or a supplemental sunblind-resistant camera, or a redundant independent forward-vision capability to satisfy critical system-failure scenarios.
Doesn't read no turn signs, it uses map data. Incorrect or not current in your case. In sections of ATL on Jan 1st ALL Right Turn on Red will become illegal. This will require a big update.Today with V12.3.6, I encountered a red light at an intersection with a "No Turn on Red" sign. My car stopped, and then attempted to make the turn. I'm assuming the sign was not properly processed, so still a few corner cases.
