VAD: Vectorized Scene Representation for Efficient Autonomous Driving

ICCV 2023poster

Autonomous driving requires a comprehensive understanding of the surrounding environment for reliable trajectory planning. Previous works rely on dense rasterized scene representation (e.g., agent occupancy and semantic map) to perform planning, which is computationally intensive and misses the inst…

Rethinking Soft Labels for Knowledge Distillation: A Bias–Variance Tradeoff Perspective

ICLR 2021poster

Knowledge distillation is an effective approach to leverage a well-trained network or an ensemble of them, named as the teacher, to guide the training of a student network. The outputs from the teacher network are used as soft labels for supervising the training of a new network. Recent studies (M…
