Hi Dhm
I have not heard this question asked before and as a result have not heard any answers however I would think we need answers to the following as well:
The first question is what is the Edge. Brainchip defines the Edge where EV's are concerned as the whole vehicle and anything that is not done on the vehicle is not being done at the Edge.
The second question what is the cost of the computing being done on a Tesla? This cost has components such as the actual cost of the architecture being used and power being consumed by it to perform these functions and on this side to what extent does the physical weight of the architecture impact the amount of power available for the driving wheels?
Certainly for most functions Tesla runs a connected network and is constantly exchanging data with the cloud however some compute must be occurring on vehicle which using Brainchip's definition is at the Edge.
The following though begs the question of how Edge is Tesla's Edge:
(from September, 2021)
"TESLA MAKES CARS. Now, it’s also the latest company to seek an edge in
artificial intelligence by making its own
silicon chips.
At
a promotional event last month,
Tesla revealed details of a custom AI chip called D1 for training the machine-learning algorithm behind its Autopilot self-driving system. The event focused on Tesla’s AI work and featured a dancing human posing as a
humanoid robot the company intends to build.
Tesla is the latest non traditional chipmaker to design its own silicon. As AI becomes more important and costly to deploy, other companies that are heavily invested in the technology—including Google, Amazon, and Microsoft—also now design their own chips.
At the event, Tesla CEO
Elon Musk said squeezing more performance out of the computer system used to train the company’s
neural network will be key to progress in autonomous driving. “If it takes a couple of days for a model to train versus a couple of hours, it’s a big deal,” he said.
Tesla already designs chips that interpret sensor input in its cars, after switching from using Nvidia hardware in 2019. But creating a powerful and complex kind of chip needed to train AI algorithms is a lot more expensive and challenging.
“If you believe that the solution to autonomous driving is training a large neural network, then what followed was exactly the kind of vertically integrated strategy you’d need,” says
Chris Gerdes, director of the
Center for Automotive Research at Stanford, who attended the Tesla event.
Many car companies use neural networks to identify objects on the road, but Tesla is relying more heavily on the technology, with a single giant neural network known as a “transformer” receiving input from eight cameras at once.
“We are effectively building a synthetic animal from the ground up,” Tesla’s AI chief, Andrej Karpathy, said during the August event. “The car can be thought of as an animal. It moves around autonomously, senses the environment and acts autonomously.”
Transformer models have provided big
advances in areas such as language understanding in recent years; the gains have come from making the models larger and more data-hungry. Training the largest AI programs
requires several million dollars worth of cloud computer power.
David Kanter, a chip analyst with Real World Technologies, says Musk is betting that by speeding the training, “then I can make this whole machine—the self-driving program—accelerate ahead of the Cruises and the Waymos of the world,” referring to two of Tesla’s rivals in autonomous driving.
Gerdes, of Stanford, says Tesla’s strategy is built around its neural network. Unlike many self-driving car companies, Tesla does not use lidar, a more expensive kind of sensor that can see the world in 3D. It relies instead on interpreting scenes by using the neural network algorithm to parse input from its cameras and radar. This is more computationally demanding because the algorithm has to reconstruct a map of its surroundings from the camera feeds rather than relying on sensors that can capture that picture directly.
But Tesla also gathers more training data than other car companies. Each of the more than 1 million Teslas on the road sends back to the company the videofeeds from its eight cameras. Tesla says it employs 1,000 people to label those images—noting cars, trucks, traffic signs, lane markings, and other features—to help train the large transformer. At the August event, Tesla also said it can automatically select which images to prioritize in labeling to make the process more efficient.
Gerdes says one risk of Tesla’s approach is that, at a certain point, adding more data may not make the system better. “Is it just a matter of more data?” he says. “Or do neural networks’ capabilities plateau at a lower level than you hope?”
Answering that question is likely to be expensive either way."
