The MAESTRO framework enhances multi-task 3D perception for autonomous driving by adaptively generating task-specific features and suppressing interference. It achieves performance superior to independently trained single-task models across 3D object detection, BEV map segmentation, and 3D occupancy prediction, while maintaining computational efficiency on the nuScenes benchmark.
Key insights
- Explicitly generating semantically guided, task-specific features from a shared backbone, rather than merely sharing features, is crucial for overcoming task conflicts in MTL.
- Adaptive enhancement and suppression mechanisms can effectively mitigate feature interference between tasks, allowing each task to focus on its most relevant information.
- Leveraging inherent task dependencies through explicit aggregation of task-oriented prototypes can foster positive knowledge transfer and improve performance for complex tasks like 3D occupancy prediction.
