MemoNav: Working Memory Model for Visual Navigation

1 code implementation CVPR 2024 Hongxin Li, Zeyu Wang, Xu Yang, Yuran Yang, Shuqi Mei, Zhaoxiang Zhang

Subsequently, a graph attention module encodes the retained STM and the LTM to generate working memory (WM) which contains the scene features essential for efficient navigation.

Visual Traffic Knowledge Graph Generation from Scene Images

no code implementations ICCV 2023 Yunfei Guo, Fei Yin, Xiao-Hui Li, Xudong Yan, Tao Xue, Shuqi Mei, Cheng-Lin Liu

Although previous works on traffic scene understanding have achieved great success, most of them stop at a lowlevel perception stage, such as road segmentation and lane detection, and few concern high-level understanding.

MemoNav: Selecting Informative Memories for Visual Navigation

no code implementations20 Aug 2022 Hongxin Li, Xu Yang, Yuran Yang, Shuqi Mei, Zhaoxiang Zhang

To address this limitation, we present the MemoNav, a novel memory mechanism for image-goal navigation, which retains the agent's informative short-term memory and long-term memory to improve the navigation performance on a multi-goal task.
