| <h2>3. The Challenge</h2> | |
| <p>The AV Causal Scenario Retrieval Challenge is a query-based video retrieval challenge focused on autonomous-driving scenarios. Given a natural-language query describing events, situations, interactions, or spatial, temporal, and causal relationships in a driving scene, a system must search a corpus of videos and return a ranked list of the clips that best match the query.</p> | |
| <p>The held-out test set spans approximately 2,000 queries evaluated against a corpus of 600+ videos. A query can match more than one clip, so systems must retrieve all relevant scenarios and rank them highly.</p> | |
| <p>For every test query, a submission produces an ordered list of video IDs. Results are measured with the several retrieval metrics as described in the challenge site.</p> | |
| <p>The challenge is built on the CASCADE dataset, which provides dense human annotations for NVIDIA's public PAI-AV Dataset. CASCADE captures hierarchical, temporally dense relationships across real-world dashcam video including multi-entity-class schemas, explicit causal links, spatial containment hierarchies, and normative compliance flags.</p> | |
| <p>Participants will submit their proposed solutions as full self-contained systems encapsulated in a docker image.</p> | |
| <p>The dataset to be used in this Challenge is a publicly available dataset identified on the Challenge Page. NVIDIA is not releasing a dataset in connection with this Challenge and participants are responsible for obtaining the dataset and complying with any applicable terms.</p> | |
