Vehicle fleet motion reconstruction using ML
Scalable scene reconstruction for recorded-driving simulations. A large-scale data pipeline processed terabytes (TBs) of tracking data across 38,000+ highway scenes, paired with a distributed training pipeline.
Industry experienceLower position error
Best-candidate average position error vs. the team’s prior baseline on approximately 58,000 held-out vehicle trajectories.
Large-scale training
12 → 3 hoursMultiple H100 graphics processing units (GPUs), PyTorch DistributedDataParallel (DDP), the NVIDIA Collective Communications Library (NCCL), and mixed precision.
