you think tesla brought the brains to that combo?Anyway, it is a pity, that Tesla and Mobileye ended their collaboration. I’m sure world would now have better autonomous cars on the road, if that was not the case.
This might be the first time I get called Tesla fan on this forumyou think tesla brought the brains to that combo?
lols
ME was right to cut tesla loose. they will advance without the liability known as tesla.
sorry fans. bitter pill to take. can your ego survive?
First things first; I don’t work on this field.Mobileye has big brains if they think two separate perception systems that fail once every 10,000 hours leads to a system with a failure every 100,000,000 hours.
I can't believe some of you claim to work in the field. It's ok though. Milton has a shiny Badger to sell to y'alls.
What is Tesla’s published failure rate of their perception system? You know, for comparison purposes.Mobileye has big brains if they think two separate perception systems that fail once every 10,000 hours leads to a system with a failure every 100,000,000 hours.

I cant believe how eager many of you are to keep proving the proverb:I can't believe some of you claim to work in the field. It's ok though. Milton has a shiny Badger to sell to y'alls.
This is an interesting issue. The two systems are independently analyzing the situation and therefore probabilities of failure are assumed to be random in each and therefore statistically uncorrelated. If that were clearly true the combined probability calculation would be defensible.Shashua is not saying that it will be exactly 100,000,000 hours per failure. He feels that it will be a good approximation. When two systems are completely independent, the odds of both systems failing at the same time, is the product of the odds of each system failing by itself. So, since both systems are close to independent, Shashua feels that the product of the odds will be a good approximation.
And the point is not to provide an exact failure rate but to give a ballpark figure that shows that having two systems will be orders of magnitude safer than having just one system.

Drug trials can be done by a third party. I can't really think of how that would work for autonomous vehicles.
The issue is that only the manufacturer has the simulation tools to figure out if a disengagement was necessary to avoid a collision. Tesla is going to have the same issue once FSD gets a few orders of magnitude better. How can an FSD beta user determine whether or not a collision would have occurred had they not disengaged?Real world data from a multitude of users over a long time span that is not curated by a vested interest.
Did you ignore the analogy to a drug clinical trial? THAT'S WHY. Happy to cite multiple examples of fudged data in this context. Safety is safety, Daniel.

Each (Vision and fused Radar/Lidar) may actually have much better than 10^-4 (1 in 10,000) failure when presented with everyday scenarios that were trained for, but significantly worse when presented with unusual, unknown and/or untrained scenarios. Thus, in the set of unusual events (edge cases as we like to call them), the probability of failure may be far higher than 10^-4 for each, and since the major causative factor was the occurrence of the edge-case scenario, that is challenging for both systems, we can reasonably conclude that the probability of edge-case failures will then not be statistically independent. This has two very important implications:
- The 10^-4 baseline assumption is invalidated for this set of edge cases (maybe it's now 10^-3 (1 in 1000) or 10^-2 (1 in 100) for this troublesome set
- Further and very importantly, we can no longer take comfort in the multiply-them-together estimation method because the cause of failure was not random between them, but exposed possible vulnerabilities of each. It is in this very set where this is likely to be true.
Shashua says that the two systems are not statistically independent and that the combined MTBF would NOT be the product of the two individual systems. What he is suggesting is that if they can achieve a goal of 10^-4 for each system, that the combined MTBF would be approximately 10x less than the product and that would be "good enough" to achieve their goal of 10x
Sounds great and all, but:
Not sure what your point is.
You're saying I twisted his words, but I didn't. It's what he says about the product of the two sensor subsystems in that video.
Yes, two sensor subsystems that are statistically independent, the total MTBF will be the product of the two MTBF. That is a true statement. And with ME's "parallel approach" to sensor fusion, ME argues that the two subsystems are approximately independent. And I showed you what Shashua said at CES 2020 that explains things in more detail. The two systems are not completely independent so the product is an approximation, not an exact number. Do some research. Don't just grab one quote from an interview.
he’s talking about the failure of the perception system, not the sensor itself. what he’s saying makes no sense in the context of perceptual predictions by self driving systems.
he says so many illogical things in that video. Even the analogy with the iOS and Android phone is a joke. it’s scary because he says all this stuff in a very believable and genuine way.
