Visually, we see a much more realistic coverage of the possible futures when scaling up the model size / training flops

Not only can we scale during training, but also at inference! By sampling more rollouts and clustering them, we can improve the performance of the model significantly. After a cross-over point of inference compute, it is best to switch to a larger model.

Most importantly (!) we show that similar to the scaling law fits for both loss and open loop metrics, closed loop performance also follows a similar scaling trend, with the number of failures decreasing as a power law when scaling pretraining compute.

Our study demonstrates that the empirical power-law scaling trend for language models, also applies to the task of motion forecasting in the autonomous vehicles domain. Besides the model being trained with teacher forcing, we observe similar scaling trends in open-loop rollouts.

Our research is driving the #AutonomousVehicle industry forward. 🚘➡️ We’ve found that #AI scaling laws hold true in AV software and real-world performance can be improved by increasing training data and compute. Take a deeper dive: https://t.co/ljFKVnTqSh
