Most questions are from BYD, Xpeng employees, I guess 😬

Thank you Dear Waymo for making this available to the world. This is really help full for both fundamental researchers and engineering specialists. Thanks. Keep up the great work.

Ashok is amazing

I will never understand why Tesla continues to put intersection cameras 9 feet behind the nose of the car and behind our backs. When there's no room to creep to see - it doesn't work! Such an obvious massive flaw. Maybe if I lived in CA with bike lanes & road buffers it would work. FIX IT

How does the network account for different calibrations on different cars? The relative poses of the 8 cameras will a little different from car to car and also drift in time and influenced by heat/cold between day and night.

Autonomous shipping? Autonomous trains?

They are hackable.

I think the most interesting thing is that Tesla's approach is really based on experimenting with ideas

Imagine this applied to military robots with guns or worse.. so Elon now has both vehicles robots and humanoid robots already where if this AI is applied to them can learn by itself with no restraints whatsoever...it is really is quite scary this needs stopping now.. even Elon himself has said it needs legislating.. and this is just the beginning.. people joke about skynet and the terminator but this is a real threat..Tesla also has the coms via Starlink .. very scary.😢😢 Elon himself in the Tucker Carlson interview available on UA-cam .... The dangers of hyper intelligent AI ... said this sort of AI unchecked could result in the annihilation of the human race ..or "civilisational destruction" as he called it .. just thinks if a mad man like Putin got hold of this tech..very very scary.

12:05 bro that was totally the Tesla’s fault. It’s the one that blew through the stop sign…

For the love of God please add radar as a data point.

Thanks to people like you and and the engineers who works at Tesla, there hope for humanity for a decent future

5 more lidars will be enough

Brilliant all the Way, thanks for the great informative video, Tesla Investors appreciate knowing just how great your work is. Also, consider how many drivers are visually challenged and still driving, or impaired drivers, or distracted drivers, the FSB is consistent and a much better option than borderline bad drivers.

Here are the key points from the video titled "[CVPR'23 WAD] Keynote - Ashok Elluswamy, Tesla": - The speaker, Ashok Elluswamy, is a member of the autopilot team at Tesla. - He presents their work on what they believe will be the foundation model for autonomy and robotics. - Tesla has shipped the full self-driving beta software to all purchasers in the United States and Canada, with roughly 400,000 vehicles having driven up to 250 million miles on the full self-driving beta program. - The self-driving stack is scalable and can navigate to any destination within the US, handling intersections, stopping at traffic lights, and interacting with other objects. - The system is driven primarily by eight cameras on the car that provide a full 360-degree coverage. - The self-driving stack is based on modern machine learning, with many components folded into neural networks. This is different from the traditional approach to self-driving, which uses localization maps and various sensors. - The system works primarily with cameras, and it performs quite well. - The speaker discusses the importance of occupancy networks in their stack, which predict whether a voxel in 3D space is occupied or not. This model task is general and robust to ontology errors. - The occupancy networks also predict the flow of voxels in the future, providing arbitrary motion. Everything runs in real time. - The architecture of the system may look complicated, but it's quite straightforward. Videos from multiple cameras stream in, and a large Transformer block builds up features and does temporal attention with some geometry thrown in. - The same architecture can be used for other tasks needed for driving, such as predicting lanes and roads. - Lanes are crucial for driving tasks but are challenging to predict due to their high-dimensional nature, graph structure, and large uncertainty. They can span the entire road, fork, merge, and sometimes even humans cannot agree on their structure. - The team uses state-of-the-art generative modeling techniques, such as autoregressive transformers, to predict lanes. This approach is similar to GPT and predicts lanes one token at a time, considering the full graph structure. - Moving objects like vehicles, trucks, and pedestrians need to be detected with their full kinematic state. The models used are multi-modal, taking in not just camera video streams but also other inputs like the vehicle's own kinematics and navigation instructions. - The entire motion planning can also be done using a network, making the system a modern machine learning stack where everything is done end-to-end. - The success of this system is attributed to the sophisticated auto-labeling pipeline that provides data from the entire fleet. This allows for multi-trip reconstruction, where multiple Tesla vehicles driving through the same location provide their video clips and kinematic data to construct the entire 3D scene. - The team uses multi-trip reconstruction to gather data from the entire fleet, enabling them to reconstruct lanes, road lines, and other elements from anywhere on Earth. - They use a hybrid approach to Neural Radiance Fields (NeRF) and general 3D reconstruction, which results in accurate and clear reconstructions of the scene, including vehicles, barriers, and trucks. - Additional neural networks are run offline to produce labels for lanes, roads, and traffic lights, creating a vector representation that can be used as labels for the online stack. - The system can auto-label traffic lights, predicting their shape, color, and relevancy, and these predictions are multi-view consistent. - These predictions provide a superhuman understanding of the world from cameras, creating a foundation model that can be used in various places. - The system helps with both autonomous and manual driving, providing emergency braking for crossing vehicles. This is a new feature, as crossing objects are harder to predict than vehicles in your own lane. - The team is working on learning a more general world model that can represent arbitrary things, using recent advances in generative models like Transformers and diffusion. - The neural network can predict future video sequences given past videos. It predicts for all eight cameras around the car jointly, understanding depth and motion on its own without any 3D priors. - The model can be action-conditioned. For example, given the same past context, when asked for different futures (like keep driving straight or change lanes), the model can produce different outcomes. - This creates a neural network simulator that can simulate different futures based on different actions, representing things that are hard to describe in an explicit system. - Future prediction tasks can also be done in semantic segmentation or reprojected to 3D spaces, predicting future 3D scenes based on the past and action prompting. - The team is working on solving various nuances of driving to build a general driving stack that can drive anywhere in the world and be human-like, fast, efficient, and safe. - Training these models requires a lot of compute power. Tesla is aiming to become a world leader in compute with their custom-built training hardware, Dojo, which is starting production soon. - The models are not just being built for the car but also for the robot, with several networks shared between the car and the robot. - The foundational models for vision that the team is building are designed to understand everything and generalize across cars and robots. They can be trained on diverse data from the fleet and require a lot of compute power. - The team is excited about the progress they expect to make in the next 12 to 18 months. - In the Q&A session, the speaker explains that they can track moving objects in the 3D reconstruction with their hybrid NeRF approach, using various cues and signals in the data. - The world model for future prediction tasks is a work in progress, but it's starting to work now, providing a simulator where they can roll out different outcomes and learn representations. - The use of autoregressive models for predicting lanes is due to the graph structure of lanes and the need to model a distribution in high-dimensional space. This approach provides clear, non-blurry predictions that are useful downstream. - The voxel size in the occupancy network output is a trade-off between memory and compute and can be configured based on the needs of the application. - The same principles of the world model should apply to humanoid robots. The model should be able to imagine what actions like picking up a cup or walking to a door would look like. - The occupancy network is used for collision avoidance in the full self-driving (FSD) system. It's particularly useful for dealing with unusual vehicles or objects that are hard to model using other methods. - The general world model is still being optimized and hasn't been shipped to customers yet. It might be ready later in the year. - The system doesn't use high-definition maps, so alignment isn't super critical. The maps used are low-definition, providing enough information to guide the network on which roads and lanes to take. This concludes the summary of the video "[CVPR'23 WAD] Keynote - Ashok Elluswamy, Tesla". The speaker, Ashok Elluswamy, discusses the development of Tesla's self-driving technology, focusing on the use of machine learning and neural networks. He also answers questions about the technical details of the system.

Too little progress compared to Ai day

12:10 the tesla missed the stop sign but ashok says the red car blew a stop sign??

3D representations can provide valuable information for self-driving systems, but they are typically used in conjunction with other sensor modalities and data sources to create a comprehensive understanding of the environment. While 3D representations, such as point clouds or voxel grids, can capture geometric details of the surroundings, they have certain limitations that make additional information necessary. Here are a few reasons why 3D representations alone may not be sufficient for self-driving: Limited Field of View: 3D representations typically rely on sensors like lidar to capture the surrounding environment. However, lidar sensors have a limited field of view and can struggle with detecting objects beyond their range or behind obstacles. Therefore, additional sensor modalities like cameras and radar are used to provide complementary information. Perception Challenges: Understanding the environment goes beyond geometry. Perception tasks like object detection, classification, and semantic segmentation require information beyond 3D representations. Cameras, for example, provide valuable color and texture information that aids in object recognition and scene understanding. Dynamic Objects: Self-driving systems need to account for the motion and behavior of dynamic objects like pedestrians, cyclists, and other vehicles. 3D representations alone may not capture the temporal aspect of these objects. Additional information, such as object tracking and prediction algorithms, are necessary to anticipate and plan for the future movements of these dynamic entities. Environmental Context: Environmental context, such as traffic signs, road markings, and traffic signals, plays a critical role in self-driving. While some aspects of this information can be captured in 3D representations, other details may require explicit detection and recognition algorithms designed for specific objects or structures. To build robust and reliable self-driving systems, it's common to integrate data from various sensors, including cameras, lidars, radars, and other sources, to create a holistic understanding of the environment. Combining multiple sensor modalities and data sources allows for redundancy, robustness in different environmental conditions, and a richer representation of the surroundings. User 3D occupancy prediction ChatGPT 3D occupancy prediction is a technique used in self-driving and robotics to estimate the occupancy or occupancy probability of the environment in three-dimensional space. It involves predicting which regions of the 3D space are occupied by obstacles or objects and which regions are free or unoccupied. This information is crucial for path planning, obstacle avoidance, and collision prevention. There are various approaches and algorithms used for 3D occupancy prediction, and here are a few common techniques: Voxel Grids: Voxel grids are a popular representation for 3D occupancy prediction. The 3D space is discretized into small volumetric cells called voxels. Each voxel can be marked as occupied, free, or unknown based on sensor measurements. Algorithms like occupancy grid mapping or probabilistic occupancy mapping can update and maintain the occupancy probabilities of the voxels over time. Point Cloud Processing: Point clouds obtained from lidar sensors are often used for 3D occupancy prediction. Various techniques, such as point cloud segmentation, clustering, and surface reconstruction, can be applied to identify and estimate the occupancy of objects in the point cloud data. Deep Learning: Deep learning methods, particularly convolutional neural networks (CNNs) and their variants, can be employed for 3D occupancy prediction. These networks can learn to directly predict occupancy probabilities or voxel-wise occupancy labels from 3D input data, such as point clouds or voxel grids. Training these models requires labeled data that indicates the occupancy status of each voxel or point. Sensor Fusion: 3D occupancy prediction can also benefit from sensor fusion, where data from multiple sensors, such as lidar, cameras, and radars, are combined to create a more comprehensive representation. Sensor fusion techniques, like Kalman filters or particle filters, can be used to integrate the data from different sensors and refine the occupancy predictions. The accuracy and reliability of 3D occupancy prediction depend on factors such as sensor quality, sensor placement, calibration, and the algorithms used. It's common to combine 3D occupancy prediction with other perception tasks, such as object detection and semantic segmentation, to create a more detailed understanding of the environment for autonomous systems.

Really enjoyed Can’t wait for autonomous mass transit buses

Nice work!

is there paper name of this work? occupancy networks

Simple. Genius. Amazing.

sad that this doesn't get the hype like gpts get, this is much cooler to me

#RemindMeIn2030: How much is TSLA worth? 🤑🤑🤑🤑🤑🤑

the dataset is great but the reader lib strictly depends on tensorflow 2.6.

Great presentation Ashok! So good to get in-depth understanding of how FSD works. Give you sense of how complex collision avoidance problem is. Thanks for great work from you and your team.

Wow we need more such of this lec!

Thanks for your valuable info

Thank you Ashok -. Great work, great presentation, and as one of those 100,000 FSD Beta drivers it’s exciting to see what’s under the hood.

Brilliant, I hope you got a lot of stock options for your work.

I like the approach. It reminds me a lot to Tesla and Comma. I wonder how you compete with these 2

very good keynote!

Very insightful, thanks!

How is the occupancy network trained? Where is the supervision coming from? As was mentioned, NeRF could be an additional way to supervise it but what is the primary supervision?

Fascinating! Note that the fake v.s. real pedestrian issue, I actually encountered it today myself! I made a video about it, at ua-cam.com/video/Dvr9qbs1PYE/v-deo.html

தமிழன் ❤️🔥

An interesting exercise is to see how many views the videos on this channel get. They're all around ~1K except the Tesla ones :D

It would be interesting to find an intersection like ua-cam.com/video/jPCV4GKX9Dw/v-deo.html where the left lane is the end of a ramp/bridge. So that looking flat and straight left would not actually indicate the correct road surface.
