The model Waymo submitted itself came thirteenth.
The category was 3D Semantic Segmentation on the Waymo Open Dataset, which measures how well a model tells one thing from another in a point cloud swept by a laser sensor.
We first learn the smallest geometric units in that cloud — points, edges, faces, holes — and then sit individual tasks such as weld seam recognition or progress measurement on top as a light layer. Adding a task does not mean retraining the whole model.
