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…

Cross-Image Relational Knowledge Distillation for Semantic Segmentation

CVPR 2022poster

Current Knowledge Distillation (KD) methods for semantic segmentation often guide the student to mimic the teacher's structured information generated from individual data samples. However, they ignore the global semantic relations among pixels across various images that are valuable for KD. This pap…

Leveraging Unimodal Self-Supervised Learning for Multimodal Audio-Visual Speech Recognition

ACL 2022long

Training Transformer-based models demands a large amount of data, while obtaining aligned and labelled data in multimodality is rather cost-demanding, especially for audio-visual speech recognition (AVSR). Thus it makes a lot of sense to make use of unlabelled unimodal data. On the other side, altho…

MixSKD: Self-Knowledge Distillation from Mixup for Image Recognition

ECCV 2022poster

"Unlike the conventional Knowledge Distillation (KD), Self-KD allows a network to learn knowledge from itself without any guidance from extra networks. This paper proposes to perform Self-KD from image Mixture (MixSKD), which integrates these two techniques into a unified framework. MixSKD mutually…

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…
