Overview
Our model adapts the GPT-like architecture for autonomous driving scenarios with two key innovations: 1) a 2D map scene tokenizer based on VQ-VAE that generates discrete, high-level representations of the 2D BEV map, and 2) a hierarchical quantization agent tokenizer to encode agent information. Using a scene-level mask, the autoregressive transformer predicts future scenes by conditioning on both ground-truth and previously predicted scene tokens during training and inference, respectively.
