CLIPDet3D: Vision-Language Collaborative Distillation for 3D Object Detection

AAAI 2026technical

Multi-view 3D object detection plays a vital role in autonomous driving systems due to its ability to perceive complex scenes accurately. However, real-world driving data often exhibits a long-tailed distribution, causing significant drops in detection accuracy for rare categories in existing method

Dynamic Label Noise Suppression with Optimal Teacher Pool for Facial Expression Recognition

CVPR 2026

Due to the inherent ambiguity of facial expressions and subjectivity in dataset labeling, learning with noisy labels remains a critical challenge in facial expression recognition (FER). The supervisory mechanism of teacher-student network offers a promising approach for noisy-labeled FER. However, t

AttAN: Attention Adversarial Networks for 3D Point Cloud Semantic Segmentation

IJCAI 2020poster

3D point cloud semantic segmentation has attracted wide attention with its extensive applications in autonomous driving, AR/VR, and robot sensing fields. However, in existing methods, each point in the segmentation results is predicted independently from each other. This property causes the non-cont…
