Elon Musk Hints at Tesla's Secret Project 'Dojo' Making the Difference in Race To Full Self-Driving (electrek.co) 122

Posted by msmash from the up-next dept.
Elon Musk set an aggressive deadline for Tesla to achieve full self-driving capability, but the electric automaker might have an ace up its sleeve that mostly went under the radar: project 'Dojo.' Electrek: Over the weekend, Musk hinted that it could make the difference. During Tesla's Autonomy Day earlier this year, Musk and other Tesla executives gave presentations about what the company is doing to try to achieve full self-driving capability by the end of next year. While most people were focused on the unveiling of Tesla's new HW3 'Full Self-Driving Computer,' which was being explained for the first time and is now installed in all new Tesla vehicles, there was a brief mention of another computer, the Dojo computer, that Tesla is working on and it could be a game-changer.

Last weekend, Musk was asked about the secret project and while the CEO didn't reveal anything new, he did hint that it could make the difference. During Autonomy Day, Musk briefly mentioned the project 'Dojo': "We do have a major program at Tesla which we don't have enough time to talk about today called "Dojo." That's a super powerful training computer. The goal of Dojo will be to be able to take in vast amounts of data and train at a video level and do unsupervised massive training of vast amounts of video with the Dojo program -- or Dojo computer."

    There was recently a talk by Andrej Karpathy [slideslive.com] in charge of the self-driving project at Tesla in which he actually discusses some of the problems with trying to tackle such a complex machine learning problem with several people working on the same neural net in today's dev tools.

    Time to train from scratch was definitely a main constraint, with people sometimes hacking the network just to avoid having to wait, like messing with file timestamps to avoid a full recompile. It sounded like full retraining took days, but shortcuts resulted in results that could not be reproduced.

    New programming paradigms, new hardware. Just like the first 3D graphics card back in the Quake days.

    Dojo might be a really nice fancy purpose built computer for training, but the real secret to Tesla's eventual success was revealed plainly at that same event.

    It's the fact that Testla can use video fragments from any Tesla anywhere for training. They can ask the entire network of cars to collect data for specific edge cases they may have discovered, then have a large training set of real world cases with real world drivers handing strange situations to learn how to react.

    People here scoff at this becoming a reality but the truth is we are really, really close to full self driving at a technical level, then we just need to worry about the regulatory side of things...

        Well, a Tesla can already park itself both parallel, and backing into a space. So really it just needs to self-drive around until it finds a space, and then use the software already written.

        You're asking the wrong questions. Why do you give a damn where the car parks, if it can drop you off at the door and come to you when you are ready to go? Does it matter if you are parked in spot #23 or spot #52?

It also won't have the person's perception of the situation, like if the sensors see a person but the driver does nothing until he abruptly jams the brakes that's probably when he saw the person. That means it's a poor idea for the AI to mimic a human because it was actually the human being sub-optimal. I suppose there's some useful data in there, but it's hardly magic.

        The edge cases can be found by searching data sets for anomalous or extreme sensor readings. Humans can review them to determine that they are what they are looking for.

        In simple terms - You show the computer how to identify them. How to react, and how not to react. If all you have are poor reactions then you explain this to the computer.
