    Supercharger - Quartzsite, AZ

    Looks like Quartzite is open and will be through thanksgiving but is having problems so charging is slow. There are 8/12 portable urban chargers present but half the regular chargers seem to be experiencing problems and are offline. Even the urbans are slowish. So if you need it it’s here but...

    Tesla autopilot HW3

    That 'monster' probably can't be run on HW2+ in a fashion that would actually drive the car. It's too big. We probably only got to see it because of an accident in the distribution system. It could be something that they were trying out in anticipation of the FSD chip coming out. Maybe we'll...

    V10 NNs

    I received a copy of the V10 networks but haven't had time to take them apart yet. My own experience is that V10's behavior is improved in some significant ways and I'm curious to see if this means that there have been changes in the nets that can be interpreted. It's worth mentioning that...

    Tesla autopilot HW3

    From the autonomy day reveal we know that Tesla had come up with a target of 50 TOPS for the FSD chip before they developed the chip back in 2016. If you build a chip with 50 TOPs it's because you want to run bigger networks - much bigger networks. AKNET_V9 is a much bigger network. That size...

    Neural Networks

    I'm in the middle of a long road trip (10k miles on AP!) so I can't offer you much detail right now, but I agree with your comments about Karpathy's history and what he's doing now at Tesla. It really looks like that V9 network (I later renamed it AKNET_V9 from the definition file label) was...

    Tesla autopilot HW3

    Why would AP2 HW be better right now than HW3? The NN compute capability of HW3 is expected to be far superior to AP2, but the architecture also changes in ways that are not a superset of what AP2 does. Because of this the NN code has to be reimplemented on the new hardware and they may...

    Tesla autopilot HW3

    HW2.0 to HW2.5 sensor changes include a different part number for the radar (from a different vendor) and different part numbers for the cameras (from the same vendor). The exact spec on the radar isn't known but a similar part number from the same vendor and a comparison to the wiring harness...

    That wasn’t intended as censure. Just an opinion. Please feel free to keep wasting time with the rest of us.

    Oh man I seriously LOL’d on that. Good one.

    Tesla autopilot HW3

    So the disconnect is that we’re comparing an unfinished L4 system to a consumer released L2 system? If manufacturers final product design intent in the discriminatory factor then you’ll get weird results when you apply it to the current operating features of an incomplete test vehicle. Does...

    I think this probably qualifies as a personal attack.

    Tesla autopilot HW3

    I agree. Producing their own NN processor required Tesla to build out a dev team and infrastructure and put money into IC development for years before the IC was ready. But all that is sunk cost and much of it was years ago - especially the risk margin. Incremental cost of fabricating units...

    Tesla autopilot HW3

    The vector unit in the patents is an accessory to the AME which expands the range of neural network layer operations that can be efficiently implemented with the AME. The AME design probably incorporates this vector unit in it's basic conception, as well as the various control systems and...

    Tesla autopilot HW3

    I had a look through the recent Tesla patent release. There's one main patent which was filed for in Sept 2017 and 3 extensions filed six months later. The main one is titled "Accelerated Mathematical Engine" - I'll attach the pdf here if I can. The others are supplemental and offer little...
