The term you’re looking for is “Federated Machine Learning.” The more cars Tesla has, the faster they can train the neural networks edge cases.

- cycrutchfield 6y agoThat’s not really what federated ml means, unless they are doing the gradient updates from the cars directly.
- f5e4 6y agoTesla does not use federated ML. Federated ML is specifically about training models on device, and is mainly a technique for preserving data privacy.
- stingraycharles 6y agoThey are collecting data on all cars yes, but are training a model in one place. That is not federated machine learning, it’s federated data collection at best.
- cbozeman 6y agoI think the massive collection of data from more and more Teslas is going to eventually allow them to produce the best self-driving vehicle. Its been a maxim of history that those with the most data generally win, whether that's military intelligence of troop movements from 2000 years ago, or LIDAR scans from a car today.
- creato 6y agoI think the best evidence for Tesla doing poorly here (or maybe that LIDAR really is necessary) is precisely that they have all this data and still aren't doing as well as others. Tesla has a seriously absurd advantage here: they can observe millions of drivers and see when the human drivers do things differently than their self driving software would have, and capture the data from those events. They've had this advantage for many years, and yet, they still don't seem to be performing that much better (if at all) than competitors.
- timkam 6y agoI agree with this concern. They collect a lot of data, sure, but they are also the only one who thinks that video is enough. It's a bold bet; intuitively, one would expect that video-only is good enough for gimmicks and fares worse when it comes to covering the millions of edge cases that still need to be addressed.
- mikejb 6y agoThis is a curious point: How much data does Tesla actually collect? I can imagine users not being too happy if their car clogs the upload for hours every time you park it in your garage?
- stingraycharles 6y agoMore than you think. There are sensors everywhere and pretty much all of them are regularly uploading telemetry to the cloud. This goes much further than self driving cars, the entire CAN bus is constantly synced with the cloud, all sensors, vibration, tire pressure, etc. All in the name of predictive maintenance and whatnot.
- joeblau 6y agoAh yeah you’re right. Distributed data collect.
- kerng 6y agoThanks for sharing. I actually hadnt heard of "federated machine learning" before- need to read up on that.
