In the field of satellite imagery, remote sensing image captioning(RSIC) is a hot topic with the challenge of overfitting and difficulty of image and text alignment. To address these issues, this paper proposes a vision-language aligning paradigm for RSIC to jointly represent vision and language. First, a new RSIC dataset DIOR-Captions is built for augmenting object detection in optical remote(DIOR) sensing images dataset with manually annotated Chinese and English contents. Second, a Vision-Language aligning model with Cross-modal Attention(VLCA) is presented to generate accurate and abundant bilingual descriptions for remote sensing images. Third, a crossmodal learning network is introduced to address the problem of visual-lingual alignment. Notably, VLCA is also applied to end-toend Chinese captions generation by using the pre-training language model of Chinese. The experiments are carried out with various baselines to validate VLCA on the proposed dataset. The results demonstrate that the proposed algorithm is more descriptive and informative than existing algorithms in producing captions.

Long-term ultra-precision synchronization between optical frequency combs(OFCs) and microwave oscillators is important for various fields, including scientific observation, smart grid, positioning and navigation, etc. Here, a phase-locked loop system based on fiber loop optical-microwave phase detector(FLOM-PD) is proposed to realize the synchronization of the repetition rate of OFCs and rubidium atomic clocks. Firstly, the scheme and locking process of the system are elaborated, then the mathematical model of the system is established, and the feasibility of the scheme is proved by theoretical analysis and experimental verification. After synchronization, the instability of the system reaches 8.69×10^(-12)at 1 s and 2.94×10^(-13)at 1 000 s, indicating that the phase synchronization system can achieve ultra-precision and stability of OFCs repetition rate.

GER-PSRO: Graph Embedding Representation based Reinforcement Learning in Sequential Colonel Blotto Game

第30届中国控制与决策会议

作者： Zhanyang Wei wanpeng zhang Jing Chen Zhen Yang College of Intelligence Science and Engineering National University of Defense Technology

We propose a novel reinforcement learning algorithm based on expert knowledge to further solve curse of dimensionality and accelerate the convergence when solving multi-robot hunting problem. Two kinds of expert knowledge are designed: one is the multi-agent joint state abstraction method based on dynamic ID, which dramatically reduces the number of state space;the other is the multi-agent Q-learning algorithm based on artificial potential field（APF）. In this method, the artificial potential field is utilized to initialize the Q value according to the environmental prior knowledge, hence the robot can acquire a better learning foundation and accelerate convergence. Finally, the proposed algorithm is validated by the multi-robot hunting problem. The results show that the method can reduce the number of state space and accelerate convergence, thus improve the performance of the algorithm.

随着我国教育事业从以普及为主的快速发展阶段进入以提高为主的高质量发展阶段,新时期社会经济以及教育改革的目标均要求义务教育财政投入的价值导向发生转变,即由公平走向充足。财政充足是以产出结果为关注点,以学生成就为核心,以一种对教学有效的方式对教育财政投入及资源使用做出的新的具体安排。本文首先论证了新时期以“公平”目标为导向的义务教育财政投入面临的挑战,进而对于“充足”的内涵进行理论分析,在此基础上从目标群体关注重点的迁移、关键对象的调整、测度原则与指标的重构三个方面阐释了构建以“充足”为价值核心的义务教育财政投入新系统的若干思考。
