The Highlights of Elon Musk's Tesla Artificial Intelligence(AI) Day - 20.08.2021
Hi, Tesla AI day was very impressive. Here are the highlights of the Tesla Artificial Intelligence day. “There’s a tremendous amount of work to make it work and that’s why we need talented people to join and solve the problem,” said Musk
Very great summary of Lex Fridman
Tesla Bot: A definitely real humanoid robot
When Tesla talks about using its advanced technology in applications outside of cars, we didn’t think he was talking about robot slaves. That’s not an exaggeration. CEO Elon Musk envisions a world in which the human drudgery like grocery shopping, “the work that people least like to do,” can be taken over by humanoid robots like the Tesla Bot. The bot is 5’8″, 125 pounds, can deadlift 150 pounds, walk at 5 miles per hour and has a screen for a head that displays important information.
“It’s intended to be friendly, of course, and navigate a world built for humans,” said Musk. “We’re setting it such that at a mechanical and physical level, you can run away from it and most likely overpower it.”
Because everyone is definitely afraid of getting beat up by a robot that’s truly had enough, right?
The bot, a prototype of which is expected for next year, is being proposed as a non-automotive robotic use case for the company’s work on neural networks and its Dojo advanced supercomputer.
D1 Chip: Unveiling of the chip to train Dojo
Tesla director Ganesh Venkataramanan unveiled Tesla’s computer chip, designed and built entirely in-house, that the company is using to run its supercomputer, Dojo. Much of Tesla’s AI architecture is dependent on Dojo, the neural network training computer that Musk says will be able to process vast amounts of camera imaging data four times faster than other computing systems. The idea is that the Dojo-trained AI software will be pushed out to Tesla customers via over-the-air updates.
The chip that Tesla revealed on Thursday is called “D1,” and it contains a 7 nm technology. Venkataramanan proudly held up the chip that he said has GPU-level compute with CPU connectivity and twice the I/O bandwidth of “the state of the art networking switch chips that are out there today and are supposed to be the gold standards.” He walked through the technicalities of the chip, explaining that Tesla wanted to own as much of its tech stack as possible to avoid any bottlenecks.
Aside from limited availability, the overall goal of taking the chip production in-house is to increase bandwidth and decrease latencies for better AI performance.
“We can do compute and data transfers simultaneously, and our custom ISA, which is the instruction set architecture, is fully optimized for machine learning workloads,” said Venkataramanan at AI Day. “This is a pure machine learning machine.”
Venkataramanan also revealed a “training tile” that integrates multiple chips to get higher bandwidth and an incredible computing power of 9 petaflops per tile and 36 terabytes per second of bandwidth. Together, the training tiles compose the Dojo supercomputer.
Supercomputer Dojo : To Full Self-Driving and beyond
Many of the speakers at the AI Day event noted that Dojo will not just be a tech for Tesla’s “Full Self-Driving” (FSD) system, it’s definitely impressive advanced driver assistance system that’s also definitely not yet fully self-driving or autonomous. The powerful supercomputer is built with multiple aspects, such as the simulation architecture, that the company hopes to expand to be universal and even open up to other automakers and tech companies.
“This is not intended to be just limited to Tesla cars,” said Musk. “Those of you who’ve seen the full self-driving beta can appreciate the rate at which the Tesla neural net is learning to drive. And this is a particular application of AI, but I think there’s more applications down the road that will make sense.”
Musk said Dojo is expected to be operational next year, at which point we can expect talk about how this tech can be applied to many other use cases.
Solving computer vision problems
Tesla’s head of AI, Andrej Karpathy, described Tesla’s architecture as “building an animal from the ground up” that moves around, senses its environment and acts intelligently and autonomously based on what it sees.
Karpathy illustrated how Tesla’s neural networks have developed over time, and how now, the visual cortex of the car, which is essentially the first part of the car’s “brain” that processes visual information, is designed in tandem with the broader neural network architecture so that information flows into the system more intelligently.
The two main problems that Tesla is working on solving with its computer vision architecture are temporary occlusions (like cars at a busy intersection blocking Autopilot’s view of the road beyond) and signs or markings that appear earlier in the road (like if a sign 100 meters back says the lanes will merge, the computer once upon a time had trouble remembering that by the time it made it to the merge lanes).
To solve for this, Tesla engineers fell back on a spatial recurring network video module, wherein different aspects of the module keep track of different aspects of the road and form a space-based and time-based queue, both of which create a cache of data that the model can refer back to when trying to make predictions about the road.
The company flexed its over 1,000-person manual data labeling team and walked the audience through how Tesla auto-labels certain clips, many of which are pulled from Tesla’s fleet on the road, in order to be able to label at scale. With all of this real-world info, the AI team then uses incredible simulation, creating “a video game with Autopilot as the player.” The simulations help particularly with data that’s difficult to source or label, or if it’s in a closed loop.
“We basically want to encourage anyone who is interested in solving real-world AI problems at either the hardware or the software level to join Tesla, or consider joining Tesla,” said Musk.
