I only have two cameras and have never confused the moon with traffic lights.

If your head was in a vice and your eyeballs were superglued into the straight-ahead position you might have more trouble.

So tesla just needs to make the cameras on their cars swivel around, Thomas the tank engine style?

I can't understand why instead of using all the possible senses: vision, auditory, radar, lidar they want to only use vision as if there's some sense of "purity" in doing that.

Which of the above would solve this problem?

Lidar could make this false prediction less likely.

That said, the computer vision is still far from human level. It lacks a common sense around how the world works.

LIDAR.

You'd be able to tell there's no object anywhere near the car and disregard the light.

Radar and Lidar perhaps, being based on reflection of radio waves/laser off surfaces.

I'm not an expert, but I'm guessing Tesla's version of lidar wouldn't detect the moon. It's probably a bit out of range.

This is a problem with learning the appropriate context. In the case of a yellow traffic light, there should be a traffic light fixture and two other (unlit) lights. Without this context, it becomes apparent the yellow pixels in a circular shape (representation to the network) are not a traffic light at all. Tesla’s vision/ml systems are amazing. I would love to learn more about how unit testing for this type of erro…

> Tesla’s vision/ml systems are amazing More importantly, they're the only ones accessible to the average consumer. Waymo/Zoox/Daimler all have equally if not more impressive systems. A real issue with tesla is that they want to be vision-only, which is going to make getting to level 5 first almost impossible. BTW - knowing where the moon is happens to be an extremely solved problem.

It's true... but I don't think that's how Tesla would solve it. Their goal is to create a neural network "driver" which can drive in any place even if it has never seen it before. They'd rather teach their neural network that the moon and stoplights are not to be confused visually. Thought I suppose in searching for training examples they could use the known position of the moon for approximate labeling.

I've definitely driven through places where there is only one light. Blinks red for stop (no stop sign). Many times, for cross traffic you'll have the one light but blinking yellow as a warning at the intersection.
