ORION: A Holistic End-to-End Autonomous Driving Framework by Vision-Language Instructed Action Generation

ICCV 2025poster

End-to-end (E2E) autonomous driving methods still struggle to make correct decisions in interactive closed-loop evaluation due to limited causal reasoning capability. Current methods attempt to leverage the powerful understanding and reasoning abilities of Vision-Language Models (VLMs) to resolve th…

RenderOcc: Vision-Centric 3D Occupancy Prediction with 2D Rendering Supervision

ICRA 2024poster

3D occupancy prediction holds significant promise in the fields of robot perception and autonomous driving, which quantifies 3D scenes into grid cells with semantic labels. Recent works mainly utilize complete occupancy labels in 3D voxel space for supervision. However, the expensive annotation proc…

SurroundSDF: Implicit 3D Scene Understanding Based on Signed Distance Field

CVPR 2024highlight

Vision-centric 3D environment understanding is both vital and challenging for autonomous driving systems. Recently object-free methods have attracted considerable attention. Such methods perceive the world by predicting the semantics of discrete voxel grids but fail to construct continuous and accur…

BEVFusion: A Simple and Robust LiDAR-Camera Fusion Framework

NeurIPS 2022accept

Fusing the camera and LiDAR information has become a de-facto standard for 3D object detection tasks. Current methods rely on point clouds from the LiDAR sensor as queries to leverage the feature from the image space. However, people discovered that this underlying assumption makes the current fusio…

Knowledge Distillation via the Target-Aware Transformer

CVPR 2022oral

Knowledge distillation becomes a de facto standard to improve the performance of small neural networks. Most of the previous works propose to regress the representational features from the teacher to the student in a one-to-one spatial matching fashion. However, people tend to overlook the fact that…

Exploring Inter-Channel Correlation for Diversity-Preserved Knowledge Distillation

ICCV 2021poster

Knowledge Distillation has shown very promising ability in transferring learned representation from the larger model (teacher) to the smaller one (student). Despite many efforts, prior methods ignore the important role of retaining inter-channel correlation of features, leading to the lack of captur…

Overflow Aware Quantization: Accelerating Neural Network Inference by Low-bit Multiply-Accumulate Operations

IJCAI 2020poster

The inherent heavy computation of deep neural networks prevents their widespread applications. A widely used method for accelerating model inference is quantization, by replacing the input operands of a network using fixed-point values. Then the majority of computation costs focus on the integer mat…
