ETPNav: Evolving Topological Planning for Vision-Language Navigation in Continuous Environments

1 code implementation6 Apr 2023 Dong An, Hanqing Wang, Wenguan Wang, Zun Wang, Yan Huang, Keji He, Liang Wang

To develop a robust VLN-CE agent, we propose a new navigation framework, ETPNav, which focuses on two critical skills: 1) the capability to abstract environments and generate long-range navigation plans, and 2) the ability of obstacle-avoiding control in continuous environments.

Time-dependent unbounded Hamiltonian simulation with vector norm scaling

no code implementations24 Dec 2020 Dong An, Di Fang, Lin Lin

We demonstrate that under suitable assumptions of the Hamiltonian and the initial vector, if the error is measured in terms of the vector norm, the computational cost may not increase at all as the norm of the Hamiltonian increases using Trotter type methods.

Maize Haploid Identification via LSTM-CNN and Hyperspectral Imaging Technology

no code implementations23 May 2018 Xuan-Yu Wang, Wen-Xuan Liao, Dong An, Yao-Guang Wei

In our study, the first attempt to design a high-accurate identification model of maize haploid seeds from diploid ones based on optimum waveband selection of the LSTM-CNN algorithm is realized via deep learning and hyperspectral imaging technology, with accuracy reaching 97% in the determining optimum waveband of 1367. 6-1526. 4nm.
