Selected Publications

Scalable Object Relation Encoding for Better 3D Spatial Reasoning in Large Language Models

  • Shengli Zhou, Minghang Zheng, Feng Zheng, Yang Liu✉
  • Accepted by CVPR 2026 / Code (GitHub)
  • This paper proposes QuatRoPE, a linear-scalable 3D positional embedding method that computes pairwise object spatial relations via quaternion rotations in Transformer attention layers, and the Isolated Gated RoPE Extension (IGRE) to minimize its interference with LLMs’ original language RoPE, while also introducing the ASR benchmark for pure 3D spatial reasoning evaluation; extensive experiments show that the proposed methods consistently boost the 3D spatial reasoning performance of LLMs on multiple 3D VL benchmarks and the ASR benchmark, outperforming strong baselines and validating their effectiveness.

Learn 3D VQA Better with Active Selection and Reannotation

  • Shengli Zhou, Yang Liu, Feng Zheng✉
  • Accepted by ACM MM 2025 / Paper (ACM Digital Library) / Paper (arXiv) / Code (GitHub)
  • To address the negative impact of inevitable improper annotation in 3D Visual Question-Answering and the scarcity of annotations, we propose a multi-turn interactive active learning strategy, combining semantic variance-based data selection with interactive oracle reannotation, enhancing answer quality and reducing training costs.

Selected Projects

When Active Learning and Data Augmentation Meet at Object Detection

  • Autonomous driving systems face challenges in real-time object detection due to high labeling costs and limited dataset diversity, prompting optimization of the RT-DETR-v2 model.
  • Integrated active learning (AL) and data augmentation to enhance detection accuracy while minimizing labeling efforts, focusing on evaluating AL strategies (random, entropy-based, information gain) and augmentation levels (e.g., motion blur, noise).
  • Achieved 75.4% mAP (6% improvement) on KITTI, validating entropy-based AL as optimal and medium-strength augmentation for balancing accuracy and real-world alignment, enabling efficient data utilization. Github

Masked-Unmasked Face Recognition

  • Face recognition struggles with brightness, angle, expression, and occlusion variations.
  • This project uses a non-deep learning approach to develop a classifier inspired by human recognition. It focuses on selecting high-quality local features to improve accuracy and reliability in face recognition. The classifier adaptively selects features based on current conditions, excluding less relevant local features to enhance recognition accuracy.
  • A mask detector with 100% accuracy on the Georgia Tech Dataset and maintaining high accuracy on harder datasets. Poster
