Memory-based Adapters for Online 3D Scene Perception

no code implementations11 Mar 2024 Xiuwei Xu, Chong Xia, Ziwei Wang, Linqing Zhao, Yueqi Duan, Jie zhou, Jiwen Lu

To this end, we propose an adapter-based plug-and-play module for the backbone of 3D scene perception model, which constructs memory to cache and aggregate the extracted RGB-D features to empower offline models with temporal learning ability.

MCUFormer: Deploying Vision Transformers on Microcontrollers with Limited Memory

1 code implementation NeurIPS 2023 Yinan Liang, Ziwei Wang, Xiuwei Xu, Yansong Tang, Jie zhou, Jiwen Lu

Due to the high price and heavy energy consumption of GPUs, deploying deep models on IoT devices such as microcontrollers makes significant contributions for ecological AI.

Anyview: Generalizable Indoor 3D Object Detection with Variable Frames

no code implementations9 Oct 2023 Zhenyu Wu, Xiuwei Xu, Ziwei Wang, Chong Xia, Linqing Zhao, Jiwen Lu, Haibin Yan

Existing methods only consider fixed frames of input data for a single detector, such as monocular RGB-D images or point clouds reconstructed from dense multi-view RGB-D images.

Embodied Task Planning with Large Language Models

1 code implementation4 Jul 2023 Zhenyu Wu, Ziwei Wang, Xiuwei Xu, Jiwen Lu, Haibin Yan

Equipping embodied agents with commonsense is important for robots to successfully complete complex human instructions in general environments.

Towards Accurate Data-free Quantization for Diffusion Models

no code implementations30 May 2023 Changyuan Wang, Ziwei Wang, Xiuwei Xu, Yansong Tang, Jie zhou, Jiwen Lu

On the contrary, we design group-wise quantization functions for activation discretization in different timesteps and sample the optimal timestep for informative calibration image generation, so that our quantized diffusion model can reduce the discretization errors with negligible computational overhead.

3D Small Object Detection with Dynamic Spatial Pruning

1 code implementation5 May 2023 Xiuwei Xu, Zhihao Sun, Ziwei Wang, Hongmin Liu, Jie zhou, Jiwen Lu

Specifically, we theoretically derive a dynamic spatial pruning (DSP) strategy to prune the redundant spatial representation of 3D scene in a cascade manner according to the distribution of objects.

Back to Reality: Weakly-supervised 3D Object Detection with Shape-guided Label Enhancement

2 code implementations CVPR 2022 Xiuwei Xu, Yifan Wang, Yu Zheng, Yongming Rao, Jie zhou, Jiwen Lu

In this paper, we propose a weakly-supervised approach for 3D object detection, which makes it possible to train a strong 3D detector with position-level annotations (i. e. annotations of object centers).
