Unleashing Generalization of End-to-End Autonomous Driving with Controllable Long Video Generation
TLDR
Delphi generates controllable long videos (up to 40 frames) to improve planning in end-to-end autonomous driving.
Reasoning
The paper presents a novel diffusion-based method for long video generation with spatial and temporal consistency, and a failure-case sampling policy to boost planning performance. Strengths include addressing data scarcity for planning tasks and achieving longer consistent videos than prior work. Weaknesses are the narrow focus on autonomous driving and lack of explicit connection to world model concepts.

Innovations
- Shared noise modeling mechanism across multi-views to increase spatial consistency in long video generation
- Feature-aligned module for precise controllability and temporal consistency
- Generation of up to 40 frames of video without loss of consistency, approximately 5 times longer than state-of-the-art methods
- Sampling policy using pre-trained visual language models to generate data similar to failure cases, improving sample efficiency
- First framework to boost planning performance of end-to-end autonomous driving models by 25% using only 4% of training dataset size
Methodology
Delphi is a diffusion-based long video generation method that employs a shared noise modeling mechanism across multiple camera views to enhance spatial consistency and a feature-aligned module to achieve precise controllability and temporal consistency. It generates up to 40 frames of video and uses a failure-case-driven sampling policy, leveraging pre-trained visual language models, to select and generate data similar to failure cases for improved sample efficiency.
Key Results
Delphi generates higher quality long videos surpassing previous state-of-the-art methods, and for the first time boosts the planning performance of an end-to-end autonomous driving model by 25% while generating only 4% of the training dataset size.
