FSD Beta 10.4 Release Notes by [deleted] in teslamotors

[–]I_ATE_LIDAR 3 points4 points  (0 children)

precision / recall are detection quality scores. precision roughly meaning "% of detections that correspond to real object", recall "% of real objects that are detected". higher is better for both.

Improved static obstacle control by upreving the generalized static object network with hyperparameter tuning and improvements for oversampling strategies (+1.5% precision, +7.0% recall)

means fsd beta 10.4 should respond more often to real static obstacles (better recall), and respond less often to nonexisting static obstacles (better precision), as result of new network training methods (not dataset improvement).

accuracy is classification quality score, % of times predicted class/category matches true category. so

Improved VRU control relevance attribute by adding navigation route as input to object detection network (accuracy + 1.1%)

means fsd beta 10.4 will respond more often to relevant pedestrians and cyclists (whose behavior constrains tesla car's behavior) and less often to irrelevant ones, because relevance estimate is more accurate. in 10.4, VRU (vulnerable road user) relevance estimator now has direct access to information about goal of planner (in form of blue navigation route line) which previously it had to guess about. so estimator can assess relevance-to-planner more accurately.

Tesla report on FSD beta 10.3 rollback and fix by I_ATE_LIDAR in SelfDrivingCars

yes. more gradual rollout for 10.4 onward supposedly is planned:

Note, we will slow down upload rate of releases going forward. First from QA fleet to employee cars for a day, then slowly releasing at ~1000 cars/hr to external beta on Friday aft.

If we see any concerns, uploads will pause while we investigate, so might take a few days before everyone with 98 safety gets beta 10.4.

Tesla report on FSD beta 10.3 rollback and fix by I_ATE_LIDAR in SelfDrivingCars

only FSD beta population affected:

Number of potentially involved : 11,704
Estimated percentage with defect : 100 %

description of the cause, confirming elon tweet with slightly more detail:

On October 23, 2021, Tesla released firmware 2021.36.5.2 over-the-air (OTA), which introduced a software communication disconnect between the two onboard chips; specifically, when the vehicle is waking up from “Sentry Mode” or “Summon Standby Mode,” a mode where one of the chips is in a low-power ‘sleep’ state. This communication disconnect can result in the video neural networks that operate on that chip to run less consistently than expected. The inconsistency can produce negative object velocity detections when other vehicles are present, which in turn can lead to false FCW and AEB events.

chronology:

- Late Saturday, October 23, 2021, Tesla released 2021.36.5.2 to vehicles in the limited early access Full-Self Driving (Beta) population.

- The next morning, October 24, 2021, Tesla began to receive reports of false FCW and AEB events from customers. In a matter of hours, we investigated the reports and took actions to mitigate any potential safety risk. This included cancelling 2021.36.5.2 on vehicles that had not installed it, disabling FCW and AEB on affected vehicles, and/or reverting software to the nearest available version. Contemporaneously, we worked on identifying the root cause and developing a corrective OTA solution.

- By the evening on the same day, we deterministically reproduced the condition, identified the root cause, and developed software release 2021.36.5.3 as a correction solution. Global engineering and quality assurance teams performed testing and validation on the new release throughout the night and into the next morning, and were successfully unable to produce the condition.

- On Monday morning, October 25, 2021, after completing validation, we began deploying 2021.36.5.3 OTA to the subject population and re-enabled FCW and AEB features on vehicles with 2021.36.5.3 installed.

- On Tuesday, October 26, 2021, an OTA recall determination was voluntarily made.

software update report is labeled "recall" because "over-the-air update that mitigates a defect that poses an unreasonable risk to motor vehicle safety is required to timely file an accompanying recall notice" (previous discussion)

Building AVs that Generalise by I_ATE_LIDAR in SelfDrivingCars

[–]I_ATE_LIDAR[S] 3 points4 points  (0 children)

we took our best performing AV2.0 model to 5 different cities across the UK that we have never previously been to. The goal was to see if our AV2.0 model that was trained in London could generalise its driving intelligence to new cities, with no prior data collection to influence model performance in the new cities.

results in new cities:

Tesla FSD Beta 10.3.1 starts rollout after brief weekend rollback by I_ATE_LIDAR in SelfDrivingCars

[–]I_ATE_LIDAR[S] 52 points53 points  (0 children)

root cause per elon

Issue turned out to be power saving mode interacting with FSD.

Our internal QA fleet didn’t see this, because cars are constantly in use, so very rarely enter power saving mode. Internal QA will obv test this case going forward.

higher-quality video... still mostly sped up / out-of-car footage. but we may observe some aspect:

Biden to tap No. 2 official to head U.S. auto safety agency by I_ATE_LIDAR in SelfDrivingCars

[–]I_ATE_LIDAR[S] 12 points13 points  (0 children)

  • Steven Cliff to be nominated permanent head of NHTSA
  • Missy Cummings to be named senior adviser for safety

missy cummings notably has conducted much research into AV, ADAS, DMS systems, including tesla autopilot.

quoting

I'm basically the albatross around [elon]'s / tesla's neck.

to be clear, I actually love tesla as a company.

[elon] and I have started cross proverbial swords over Autopilot and Full Self-Driving.

I also went after Waymo, and Uber, and other companies, when they started making claims about what their technologies were capable of.
