Sending sensor data to the cloud for offline processing to improve machine learning models.

Data Requirements for Self-Driving Cars:
Self-driving cars need vast amounts of data to train their machine learning algorithms. This data includes sensor data (images, lidar, radar), object movement data, and mapping data. Mapping data must be highly accurate and precise to ensure the car’s location awareness.

Challenges in Creating and Managing Data:
Self-driving car companies often lack the expertise and resources to efficiently handle data labeling and annotation. These tasks require specialized knowledge and can be a significant distraction from the core competencies of these companies.

Types of Labels Required:
Labeling involves identifying and marking specific objects in sensor data. Common labels include masks around vehicles, pedestrians, and traffic signs.

Waymo’s Approach to Training and Simulation:
Waymo uses a combination of real-world and virtual simulations for training its self-driving cars. This includes recreating challenging scenarios and circumstances to improve the car’s response to unusual situations.

Learning About the Self-Driving Car Development Process:
The field of self-driving cars is relatively shallow, with much of the information publicly available. Academia plays a significant role in research and development, and many experts from academia join private companies. Keeping up with developments and talking to people in the field can provide valuable insights into the industry.

Flexibility in Labeling Pipeline:
As an API company, our platform offers flexibility in data submission. Customers can send data for labeling whenever they want, either automatically or manually, as per their preference.

Workflow for Self-Driving Car Data Annotation:
Companies collect and send data to Scale API for labeling. Once initial data is labeled, companies send poorly performing situations to Scale API for further labeling. This iterative cycle continues to improve the efficiency of self-driving vehicles.

Labeling Requirements:
Companies care about labeling anything a human driver would see and consider while driving. This includes cars, pedestrians, stop signs, street signs, lights, obstacles, construction, cyclists, motorcyclists, and debris. Lane markings are also labeled to understand lane structures.

Training and Benchmarking:
Annotated data is used for training self-driving car systems and benchmarking their performance. Computer-generated labels are compared to human-generated labels to identify areas of improvement.

Edge Cases and Unseen Situations:
Deep learning systems can make unexpected mistakes even in seemingly normal situations. Models struggle in situations they haven’t encountered or been trained on. Extrapolating beyond the training data can lead to poor performance in different environments, such as moving from San Francisco to New York.

Focus of the Company:
The company’s primary focus is to identify tasks where they can make a significant impact on customers, ideally in growing industries.

Choice of Self-Driving Cars:
Self-driving cars were chosen due to the massive trend of AI, the availability of technology, and the significant bottleneck in access to labeled data and machine learning talent.

Goal of the Company:
The company’s ultimate goal is to help artificial intelligence realize its potential by addressing the data labeling bottleneck.

Sensor Fusion Annotation:
Self-driving cars have a variety of sensors, each providing different information. LiDAR provides 3D depth perception, while images recognize objects near and far. Sensors provide redundancy, verifying objects across different sensors and improving accuracy. The company’s sensor fusion product allows companies to combine and label data from all sensors.

Labeling Process:
The company’s labelers annotate data from various sensors, including LiDAR, radar, and camera images. Sensors are sometimes split among different labelers for efficiency, but sometimes a single labeler handles multiple sensors for better quality. The results are combined and sent back to the client.

Onboarding Process:
Scale uses an API-first approach, enabling easy onboarding for developers. Developers interact with the API docs and test API keys.

Data Labeling:
Companies send image, LiDAR, or radar data through the API for labeling. Scale combines machine learning and human workers for efficient labeling. Labeled data is returned to companies via callback.

Machine Learning:
Scale employs machine learning on its platform to assist in labeling tasks. This speeds up the labeling process and improves accuracy.

Importance of Automation:
Manual labeling for self-driving cars is not feasible due to the vast amount of data. Examples of manual labeling in Google Maps and Facebook’s content moderation. Over time, automation was introduced to improve efficiency.

Alphabet as a Customer:
Alphabet has core competencies in label data production. However, internal processes can be slow and hinder innovation. Scale offers better response times, quality, and API, making it a preferred choice.

Cost Savings:
Using Scale can save money compared to internal labeling processes. Reduced time spent on internal team coordination and task management.

End-to-End Labeling Process:
A company sends LiDAR and radar data through the API to identify bikers and pedestrians. Scale’s platform combines machine learning and human workers to label the data. Labeled data is returned to the company via callback.

General Approach to Handling Requests:
Requests are initially evaluated by machine learning algorithms, and if needed, they are passed to human evaluators for quality verification. Pre-processing and post-processing steps are applied to the data to ensure proper ingestion, display, and return.

Infrastructure Types:
