Commonsense Prototype for Outdoor Unsupervised 3D Object Detection

1 code implementation25 Apr 2024 Hai Wu, Shijia Zhao, Xun Huang, Chenglu Wen, Xin Li, Cheng Wang

The prevalent approaches of unsupervised 3D object detection follow cluster-based pseudo-label generation and iterative self-training processes.

Sunshine to Rainstorm: Cross-Weather Knowledge Distillation for Robust 3D Object Detection

1 code implementation28 Feb 2024 Xun Huang, Hai Wu, Xin Li, Xiaoliang Fan, Chenglu Wen, Cheng Wang

LiDAR-based 3D object detection models have traditionally struggled under rainy conditions due to the degraded and noisy scanning signals.

Efficient Multiuser AI Downloading via Reusable Knowledge Broadcasting

no code implementations28 Jul 2023 Hai Wu, Qunsong Zeng, Kaibin Huang

To overcome the bottleneck, we propose the framework of model broadcasting and assembling (MBA), which represents the first attempt on leveraging reusable knowledge, referring to shared parameters among tasks, to enable parameter broadcasting to reduce communication overhead.

CoIn: Contrastive Instance Feature Mining for Outdoor 3D Object Detection with Very Limited Annotations

1 code implementation ICCV 2023 Qiming Xia, Jinhao Deng, Chenglu Wen, Hai Wu, Shaoshuai Shi, Xin Li, Cheng Wang

Combining CoIn with an iterative training strategy, we propose a CoIn++ pipeline, which requires only 2% annotations in the KITTI dataset to achieve performance comparable to the fully supervised methods.

Vertical Layering of Quantized Neural Networks for Heterogeneous Inference

no code implementations10 Dec 2022 Hai Wu, Ruifei He, Haoru Tan, Xiaojuan Qi, Kaibin Huang

Experiments show that the proposed vertical-layered representation and developed once QAT scheme are effective in embodying multiple quantized networks into a single one and allow one-time training, and it delivers comparable performance as that of quantized models tailored to any specific bit-width.

Transformation-Equivariant 3D Object Detection for Autonomous Driving

no code implementations22 Nov 2022 Hai Wu, Chenglu Wen, Wei Li, Xin Li, Ruigang Yang, Cheng Wang

However, it is difficult to apply such networks to 3D object detection in autonomous driving due to its large computation cost and slow reasoning speed.

In-situ Model Downloading to Realize Versatile Edge AI in 6G Mobile Networks

no code implementations7 Oct 2022 Kaibin Huang, Hai Wu, Zhiyan Liu, Xiaojuan Qi

We further propose a virtualized 6G network architecture customized for deploying in-situ model downloading with the key feature of a three-tier (edge, local, and central) AI library.
